/**
 * An injectable service that produces an animation sequence programmatically within an
 * Angular component or directive.
 * Provided by the `BrowserAnimationsModule` or `NoopAnimationsModule`.
 *
 * @usageNotes
 *
 * To use this service, add it to your component or directive as a dependency.
 * The service is instantiated along with your component.
 *
 * Apps do not typically need to create their own animation players, but if you
 * do need to, follow these steps:
 *
 * 1. Use the `build()` method to create a programmatic animation using the
 * `animate()` function. The method returns an `AnimationFactory` instance.
 *
 * 2. Use the factory object to create an `AnimationPlayer` and attach it to a DOM element.
 *
 * 3. Use the player object to control the animation programmatically.
 *
 * For example:
 *
 * ```ts
 * // import the service from BrowserAnimationsModule
 * import {AnimationBuilder} from '@angular/animations';
 * // require the service as a dependency
 * class MyCmp {
 *   constructor(private _builder: AnimationBuilder) {}
 *
 *   makeAnimation(element: any) {
 *     // first define a reusable animation
 *     const myAnimation = this._builder.build([
 *       style({ width: 0 }),
 *       animate(1000, style({ width: '100px' }))
 *     ]);
 *
 *     // use the returned factory object to create a player
 *     const player = myAnimation.create(element);
 *
 *     player.play();
 *   }
 * }
 * ```

/**
 * Creates a named animation trigger, containing a  list of `state()`
 * and `transition()` entries to be evaluated when the expression
 * bound to the trigger changes.
 *
 * @param name An identifying string.
 * @param definitions  An animation definition object, containing an array of `state()`
 * and `transition()` declarations.
 *
 * @return An object that encapsulates the trigger data.
 *
 * @usageNotes
 * Define an animation trigger in the `animations` section of `@Component` metadata.
 * In the template, reference the trigger by name and bind it to a trigger expression that
 * evaluates to a defined animation state, using the following format:
 *
 * `[@triggerName]="expression"`
 *
 * Animation trigger bindings convert all values to strings, and then match the
 * previous and current values against any linked transitions.
 * Booleans can be specified as `1` or `true` and `0` or `false`.
 *
 * ### Usage Example
 *
 * The following example creates an animation trigger reference based on the provided
 * name value.
 * The provided animation value is expected to be an array consisting of state and
 * transition declarations.
 *
 * ```typescript
 * @Component({
 *   selector: "my-component",
 *   templateUrl: "my-component-tpl.html",
 *   animations: [
 *     trigger("myAnimationTrigger", [
 *       state(...),
 *       state(...),
 *       transition(...),
 *       transition(...)
 *     ])
 *   ]
 * })
 * class MyComponent {
 *   myStatusExp = "something";
 * }
 * ```
 *
 * The template associated with this component makes use of the defined trigger
 * by binding to an element within its template code.
 *
 * ```html
 * <!-- somewhere inside of my-component-tpl.html -->
 * <div [@myAnimationTrigger]="myStatusExp">...</div>
 * ```
 *
 * ### Using an inline function
 * The `transition` animation method also supports reading an inline function which can decide
 * if its associated animation should be run.
 *
 * ```typescript
 * // this method is run each time the `myAnimationTrigger` trigger value changes.
 * function myInlineMatcherFn(fromState: string, toState: string, element: any, params: {[key:
 string]: any}): boolean {
 *   // notice that `element` and `params` are also available here
 *   return toState == 'yes-please-animate';
 * }
 *
 * @Component({
 *   selector: 'my-component',
 *   templateUrl: 'my-component-tpl.html',
 *   animations: [
 *     trigger('myAnimationTrigger', [
 *       transition(myInlineMatcherFn, [
 *         // the animation sequence code
 *       ]),
 *     ])
 *   ]
 * })
 * class MyComponent {
 *   myStatusExp = "yes-please-animate";
 * }
 * ```
 *
 * ### Disabling Animations
 * When true, the special animation control binding `@.disabled` binding prevents
 * all animations from rendering.
 * Place the  `@.disabled` binding on an element to disable
 * animations on the element itself, as well as any inner animation triggers
 * within the element.
 *
 * The following example shows how to use this feature:
 *
 * ```typescript
 * @Component({
 *   selector: 'my-component',
 *   template: `
 *     <div [@.disabled]="isDisabled">
 *       <div [@childAnimation]="exp"></div>
 *     </div>
 *   `,
 *   animations: [
 *     trigger("childAnimation", [
 *       // ...
 *     ])
 *   ]
 * })
 * class MyComponent {
 *   isDisabled = true;
 *   exp = '...';
 * }
 * ```
 *
 * When `@.disabled` is true, it prevents the `@childAnimation` trigger from animating,
 * along with any inner animations.
 *
 * ### Disable animations application-wide
 * When an area of the template is set to have animations disabled,
 * **all** inner components have their animations disabled as well.
 * This means that you can disable all animations for an app
 * by placing a host binding set on `@.disabled` on the topmost Angular component.
 *
 * ```typescript
 * import {Component, HostBinding} from '@angular/core';
 *
 * @Component({
 *   selector: 'app-component',
 *   templateUrl: 'app.component.html',
 * })
 * class AppComponent {
 *   @HostBinding('@.disabled')
 *   public animationsDisabled = true;
 * }
 * ```
 *
 * ### Overriding disablement of inner animations
 * Despite inner animations being disabled, a parent animation can `query()`
 * for inner elements located in disabled areas of the template and still animate
 * them if needed. This is also the case for when a sub animation is
 * queried by a parent and then later animated using `animateChild()`.
 *
 * ### Detecting when an animation is disabled
 * If a region of the DOM (or the entire application) has its animations disabled, the animation
 * trigger callbacks still fire, but for zero seconds. When the callback fires, it provides
 * an instance of an `AnimationEvent`. If animations are disabled,
 * the `.disabled` flag on the event is true.
 *

/**
 * Defines an animation step that combines styling information with timing information.
 *
 * @param timings Sets `AnimateTimings` for the parent animation.
 * A string in the format "duration [delay] [easing]".
 *  - Duration and delay are expressed as a number and optional time unit,
 * such as "1s" or "10ms" for one second and 10 milliseconds, respectively.
 * The default unit is milliseconds.
 *  - The easing value controls how the animation accelerates and decelerates
 * during its runtime. Value is one of  `ease`, `ease-in`, `ease-out`,
 * `ease-in-out`, or a `cubic-bezier()` function call.
 * If not supplied, no easing is applied.
 *
 * For example, the string "1s 100ms ease-out" specifies a duration of
 * 1000 milliseconds, and delay of 100 ms, and the "ease-out" easing style,
 * which decelerates near the end of the duration.
 * @param styles Sets AnimationStyles for the parent animation.
 * A function call to either `style()` or `keyframes()`
 * that returns a collection of CSS style entries to be applied to the parent animation.
 * When null, uses the styles from the destination state.
 * This is useful when describing an animation step that will complete an animation;
 * see "Animating to the final state" in `transitions()`.
 * @returns An object that encapsulates the animation step.
 *
 * @usageNotes
 * Call within an animation `sequence()`, `{@link animations/group group()}`, or
 * `transition()` call to specify an animation step
 * that applies given style data to the parent animation for a given amount of time.
 *
 * ### Syntax Examples
 * **Timing examples**
 *
 * The following examples show various `timings` specifications.
 * - `animate(500)` : Duration is 500 milliseconds.
 * - `animate("1s")` : Duration is 1000 milliseconds.
 * - `animate("100ms 0.5s")` : Duration is 100 milliseconds, delay is 500 milliseconds.
 * - `animate("5s ease-in")` : Duration is 5000 milliseconds, easing in.
 * - `animate("5s 10ms cubic-bezier(.17,.67,.88,.1)")` : Duration is 5000 milliseconds, delay is 10
 * milliseconds, easing according to a bezier curve.
 *
 * **Style examples**
 *
 * The following example calls `style()` to set a single CSS style.
 * ```typescript
 * animate(500, style({ background: "red" }))
 * ```
 * The following example calls `keyframes()` to set a CSS style
 * to different values for successive keyframes.
 * ```typescript
 * animate(500, keyframes(
 *  [
 *   style({ background: "blue" }),
 *   style({ background: "red" })
 *  ])
 * ```

 * within the animation arc.
 * Compare [CSS Keyframe Animations](https://www.w3schools.com/css/css3_animations.asp).
 *
 * ### Usage
 *
 * In the following example, the offset values describe
 * when each `backgroundColor` value is applied. The color is red at the start, and changes to

/**
 * Declares an animation transition as a sequence of animation steps to run when a given
 * condition is satisfied. The condition is a Boolean expression or function that compares
 * the previous and current animation states, and returns true if this transition should occur.
 * When the state criteria of a defined transition are met, the associated animation is
 * triggered.
 *
 * @param stateChangeExpr A Boolean expression or function that compares the previous and current
 * animation states, and returns true if this transition should occur. Note that  "true" and "false"
 * match 1 and 0, respectively. An expression is evaluated each time a state change occurs in the
 * animation trigger element.
 * The animation steps run when the expression evaluates to true.
 *
 * - A state-change string takes the form "state1 => state2", where each side is a defined animation
 * state, or an asterix (*) to refer to a dynamic start or end state.
 *   - The expression string can contain multiple comma-separated statements;
 * for example "state1 => state2, state3 => state4".
 *   - Special values `:enter` and `:leave` initiate a transition on the entry and exit states,
 * equivalent to  "void => *"  and "* => void".
 *   - Special values `:increment` and `:decrement` initiate a transition when a numeric value has
 * increased or decreased in value.
 * - A function is executed each time a state change occurs in the animation trigger element.
 * The animation steps run when the function returns true.
 *
 * @param steps One or more animation objects, as returned by the `animate()` or
 * `sequence()` function, that form a transformation from one state to another.
 * A sequence is used by default when you pass an array.
 * @param options An options object that can contain a delay value for the start of the animation,
 * and additional developer-defined parameters. Provided values for additional parameters are used
 * as defaults, and override values can be passed to the caller on invocation.
 * @returns An object that encapsulates the transition data.
 *
 * @usageNotes
 * The template associated with a component binds an animation trigger to an element.
 *
 * ```HTML
 * <!-- somewhere inside of my-component-tpl.html -->
 * <div [@myAnimationTrigger]="myStatusExp">...</div>
 * ```
 *
 * All transitions are defined within an animation trigger,
 * along with named states that the transitions change to and from.
 *
 * ```typescript
 * trigger("myAnimationTrigger", [
 *  // define states
 *  state("on", style({ background: "green" })),
 *  state("off", style({ background: "grey" })),
 *  ...]
 * ```
 *
 * Note that when you call the `sequence()` function within a `{@link animations/group group()}`
 * or a `transition()` call, execution does not continue to the next instruction
 * until each of the inner animation steps have completed.
 *
 * ### Syntax examples
 *
 * The following examples define transitions between the two defined states (and default states),
 * using various options:
 *
 * ```typescript
 * // Transition occurs when the state value
 * // bound to "myAnimationTrigger" changes from "on" to "off"
 * transition("on => off", animate(500))
 * // Run the same animation for both directions
 * transition("on <=> off", animate(500))
 * // Define multiple state-change pairs separated by commas
 * transition("on => off, off => void", animate(500))
 * ```
 *
 * ### Special values for state-change expressions
 *
 * - Catch-all state change for when an element is inserted into the page and the
 * destination state is unknown:
 *
 * ```typescript
 * transition("void => *", [
 *  style({ opacity: 0 }),
 *  animate(500)
 *  ])
 * ```
 *
 * - Capture a state change between any states:
 *
 *  `transition("* => *", animate("1s 0s"))`
 *
 * - Entry and exit transitions:
 *
 * ```typescript
 * transition(":enter", [
 *   style({ opacity: 0 }),
 *   animate(500, style({ opacity: 1 }))
 *   ]),
 * transition(":leave", [
 *   animate(500, style({ opacity: 0 }))
 *   ])
 * ```
 *
 * - Use `:increment` and `:decrement` to initiate transitions:
 *
 * ```typescript
 * transition(":increment", group([
 *  query(':enter', [
 *     style({ left: '100%' }),
 *     animate('0.5s ease-out', style('*'))
 *   ]),
 *  query(':leave', [
 *     animate('0.5s ease-out', style({ left: '-100%' }))
 *  ])
 * ]))
 *
 * transition(":decrement", group([
 *  query(':enter', [
 *     style({ left: '100%' }),
 *     animate('0.5s ease-out', style('*'))
 *   ]),
 *  query(':leave', [
 *     animate('0.5s ease-out', style({ left: '-100%' }))
 *  ])
 * ]))
 * ```
 *
 * ### State-change functions
 *
 * Here is an example of a `fromState` specified as a state-change function that invokes an
 * animation when true:
 *
 * ```typescript
 * transition((fromState, toState) =>
 *  {
 *   return fromState == "off" && toState == "on";
 *  },
 *  animate("1s 0s"))
 * ```
 *
 * ### Animating to the final state
 *
 * If the final step in a transition is a call to `animate()` that uses a timing value
 * with no style data, that step is automatically considered the final animation arc,
 * for the element to reach the final state. Angular automatically adds or removes
 * CSS styles to ensure that the element is in the correct final state.
 *
 * The following example defines a transition that starts by hiding the element,
 * then makes sure that it animates properly to whatever state is currently active for trigger:
 *
 * ```typescript
 * transition("void => *", [
 *   style({ opacity: 0 }),
 *   animate(500)
 *  ])
 * ```
 * ### Boolean value matching
 * If a trigger binding value is a Boolean, it can be matched using a transition expression
 * that compares true and false or 1 and 0. For example:
 *
 * ```
 * // in the template
 * <div [@openClose]="open ? true : false">...</div>
 * // in the component metadata
 * trigger('openClose', [
 *   state('true', style({ height: '*' })),
 *   state('false', style({ height: '0px' })),
 *   transition('false <=> true', animate(500))
 * ])
 * ```

/**
 * Finds one or more inner elements within the current element that is
 * being animated within a sequence. Use with `animate()`.
 *
 * @param selector The element to query, or a set of elements that contain Angular-specific
 * characteristics, specified with one or more of the following tokens.
 *  - `query(":enter")` or `query(":leave")` : Query for newly inserted/removed elements.
 *  - `query(":animating")` : Query all currently animating elements.
 *  - `query("@triggerName")` : Query elements that contain an animation trigger.
 *  - `query("@*")` : Query all elements that contain an animation triggers.
 *  - `query(":self")` : Include the current element into the animation sequence.
 *
 * @param animation One or more animation steps to apply to the queried element or elements.
 * An array is treated as an animation sequence.
 * @param options An options object. Use the 'limit' field to limit the total number of
 * items to collect.
 * @return An object that encapsulates the query data.
 *
 * @usageNotes
 * Tokens can be merged into a combined query selector string. For example:
 *
 * ```typescript
 *  query(':self, .record:enter, .record:leave, @subTrigger', [...])
 * ```
 *
 * The `query()` function collects multiple elements and works internally by using
 * `element.querySelectorAll`. Use the `limit` field of an options object to limit
 * the total number of items to be collected. For example:
 *
 * ```js
 * query('div', [
 *   animate(...),
 *   animate(...)
 * ], { limit: 1 })
 * ```
 *
 * By default, throws an error when zero items are found. Set the
 * `optional` flag to ignore this error. For example:
 *
 * ```js
 * query('.some-element-that-may-not-be-there', [
 *   animate(...),
 *   animate(...)
 * ], { optional: true })
 * ```
 *
 * ### Usage Example
 *
 * The following example queries for inner elements and animates them
 * individually using `animate()`.
 *
 * ```typescript
 * @Component({
 *   selector: 'inner',
 *   template: `
 *     <div [@queryAnimation]="exp">
 *       <h1>Title</h1>
 *       <div class="content">
 *         Blah blah blah
 *       </div>
 *     </div>
 *   `,
 *   animations: [
 *    trigger('queryAnimation', [
 *      transition('* => goAnimate', [
 *        // hide the inner elements
 *        query('h1', style({ opacity: 0 })),
 *        query('.content', style({ opacity: 0 })),
 *
 *        // animate the inner elements in, one by one
 *        query('h1', animate(1000, style({ opacity: 1 }))),
 *        query('.content', animate(1000, style({ opacity: 1 }))),
 *      ])
 *    ])
 *  ]
 * })
 * class Cmp {
 *   exp = '';
 *
 *   goAnimate() {
 *     this.exp = 'goAnimate';
 *   }
 * }
 * ```

/**
 * Use within an animation `query()` call to issue a timing gap after
 * each queried item is animated.
 *
 * @param timings A delay value.
 * @param animation One ore more animation steps.
 * @returns An object that encapsulates the stagger data.
 *
 * @usageNotes
 * In the following example, a container element wraps a list of items stamped out
 * by an `ngFor`. The container element contains an animation trigger that will later be set
 * to query for each of the inner items.
 *
 * Each time items are added, the opacity fade-in animation runs,
 * and each removed item is faded out.
 * When either of these animations occur, the stagger effect is
 * applied after each item's animation is started.
 *
 * ```html
 * <!-- list.component.html -->
 * <button (click)="toggle()">Show / Hide Items</button>
 * <hr />
 * <div [@listAnimation]="items.length">
 *   <div *ngFor="let item of items">
 *     {{ item }}
 *   </div>
 * </div>
 * ```
 *
 * Here is the component code:
 *
 * ```typescript
 * import {trigger, transition, style, animate, query, stagger} from '@angular/animations';
 * @Component({
 *   templateUrl: 'list.component.html',
 *   animations: [
 *     trigger('listAnimation', [
 *     ...
 *     ])
 *   ]
 * })
 * class ListComponent {
 *   items = [];
 *
 *   showItems() {
 *     this.items = [0,1,2,3,4];
 *   }
 *
 *   hideItems() {
 *     this.items = [];
 *   }
 *
 *   toggle() {
 *     this.items.length ? this.hideItems() : this.showItems();
 *    }
 *  }
 * ```
 *
 * Here is the animation trigger code:
 *
 * ```typescript
 * trigger('listAnimation', [
 *   transition('* => *', [ // each time the binding value changes
 *     query(':leave', [
 *       stagger(100, [
 *         animate('0.5s', style({ opacity: 0 }))
 *       ])
 *     ]),

 *       style({ opacity: 0 }),
 *       stagger(100, [
 *         animate('0.5s', style({ opacity: 1 }))
 *       ])
 *     ])
 *   ])

/*
 * [Validation]
 * The visitor code below will traverse the animation AST generated by the animation verb functions
 * (the output is a tree of objects) and attempt to perform a series of validations on the data. The
 * following corner-cases will be validated:
 *
 * 1. Overlap of animations
 * Given that a CSS property cannot be animated in more than one place at the same time, it's
 * important that this behavior is detected and validated. The way in which this occurs is that
 * each time a style property is examined, a string-map containing the property will be updated with
 * the start and end times for when the property is used within an animation step.
 *
 * If there are two or more parallel animations that are currently running (these are invoked by the
 * group()) on the same element then the validator will throw an error. Since the start/end timing
 * values are collected for each property then if the current animation step is animating the same
 * property and its timing values fall anywhere into the window of time that the property is
 * currently being animated within then this is what causes an error.
 *
 * 2. Timing values
 * The validator will validate to see if a timing value of `duration delay easing` or
 * `durationNumber` is valid or not.
 *
 * (note that upon validation the code below will replace the timing data with an object containing
 * {duration,delay,easing}.
 *
 * 3. Offset Validation
 * Each of the style() calls are allowed to have an offset value when placed inside of keyframes().
 * Offsets within keyframes() are considered valid when:
 *
 *   - No offsets are used at all
 *   - Each style() entry contains an offset value
 *   - Each offset is between 0 and 1
 *   - Each offset is greater to or equal than the previous one
 *
 * Otherwise an error will be thrown.

/*
 * The code within this file aims to generate web-animations-compatible keyframes from Angular's
 * animation DSL code.
 *
 * The code below will be converted from:
 *
 * ```
 * sequence([
 *   style({ opacity: 0 }),
 *   animate(1000, style({ opacity: 0 }))
 * ])
 * ```
 *
 * To:
 * ```
 * keyframes = [{ opacity: 0, offset: 0 }, { opacity: 1, offset: 1 }]
 * duration = 1000
 * delay = 0
 * easing = ''
 * ```
 *
 * For this operation to cover the combination of animation verbs (style, animate, group, etc...) a
 * combination of prototypical inheritance, AST traversal and merge-sort-like algorithms are used.
 *
 * [AST Traversal]
 * Each of the animation verbs, when executed, will return an string-map object representing what
 * type of action it is (style, animate, group, etc...) and the data associated with it. This means
 * that when functional composition mix of these functions is evaluated (like in the example above)
 * then it will end up producing a tree of objects representing the animation itself.
 *
 * When this animation object tree is processed by the visitor code below it will visit each of the
 * verb statements within the visitor. And during each visit it will build the context of the
 * animation keyframes by interacting with the `TimelineBuilder`.
 *
 * [TimelineBuilder]
 * This class is responsible for tracking the styles and building a series of keyframe objects for a
 * timeline between a start and end time. The builder starts off with an initial timeline and each
 * time the AST comes across a `group()`, `keyframes()` or a combination of the two wihtin a
 * `sequence()` then it will generate a sub timeline for each step as well as a new one after
 * they are complete.
 *
 * As the AST is traversed, the timing state on each of the timelines will be incremented. If a sub
 * timeline was created (based on one of the cases above) then the parent timeline will attempt to
 * merge the styles used within the sub timelines into itself (only with group() this will happen).
 * This happens with a merge operation (much like how the merge works in mergesort) and it will only
 * copy the most recently used styles from the sub timelines into the parent timeline. This ensures
 * that if the styles are used later on in another phase of the animation then they will be the most
 * up-to-date values.
 *
 * [How Missing Styles Are Updated]
 * Each timeline has a `backFill` property which is responsible for filling in new styles into
 * already processed keyframes if a new style shows up later within the animation sequence.
 *
 * ```
 * sequence([
 *   style({ width: 0 }),
 *   animate(1000, style({ width: 100 })),
 *   animate(1000, style({ width: 200 })),
 *   animate(1000, style({ width: 300 }))
 *   animate(1000, style({ width: 400, height: 400 })) // notice how `height` doesn't exist anywhere
 * else
 * ])
 * ```
 *
 * What is happening here is that the `height` value is added later in the sequence, but is missing
 * from all previous animation steps. Therefore when a keyframe is created it would also be missing
 * from all previous keyframes up until where it is first used. For the timeline keyframe generation
 * to properly fill in the style it will place the previous value (the value from the parent
 * timeline) or a default value of `*` into the backFill object. Given that each of the keyframe
 * styles are objects that prototypically inhert from the backFill object, this means that if a
 * value is added into the backFill then it will automatically propagate any missing values to all
 * keyframes. Therefore the missing `height` value will be properly filled into the already
 * processed keyframes.
 *
 * When a sub-timeline is created it will have its own backFill property. This is done so that
 * styles present within the sub-timeline do not accidentally seep into the previous/future timeline
 * keyframes
 *
 * (For prototypically-inherited contents to be detected a `for(i in obj)` loop must be used.)
 *
 * [Validation]
 * The code in this file is not responsible for validation. That functionality happens with within
 * the `AnimationValidatorVisitor` code.

 * @description
 *
 * A service that applications can use to interact with a browser's URL.
 *
 * Depending on the `LocationStrategy` used, `Location` persists
 * to the URL's path or the URL's hash segment.
 *
 * @usageNotes
 *
 * It's better to use the `Router.navigate()` service to trigger route changes. Use
 * `Location` only if you need to interact with or create normalized URLs outside of
 * routing.
 *
 * `Location` is responsible for normalizing the URL against the application's base href.
 * A normalized URL is absolute from the URL host, includes the application's base href, and has no
 * trailing slash:
 * - `/my/app/user/123` is normalized
 * - `my/app/user/123` **is not** normalized

 * Instantiates a {@link Component} type and inserts its Host View into the current View.
 * `NgComponentOutlet` provides a declarative approach for dynamic component creation.
 *
 * `NgComponentOutlet` requires a component type, if a falsy value is set the view will clear and
 * any existing component will be destroyed.
 *
 * @usageNotes
 *
 * ### Fine tune control
 *
 * You can control the component creation process by using the following optional attributes:
 *
 * * `ngComponentOutletInjector`: Optional custom {@link Injector} that will be used as parent for
 * the Component. Defaults to the injector of the current view container.
 *
 * * `ngComponentOutletContent`: Optional list of projectable nodes to insert into the content
 * section of the component, if it exists.
 *
 * * `ngComponentOutletNgModuleFactory`: Optional module factory to allow loading another
 * module dynamically, then loading a component from that module.
 *
 * ### Syntax
 *
 * Simple
 * ```
 * <ng-container *ngComponentOutlet="componentTypeExpression"></ng-container>
 * ```
 *
 * Customized injector/content
 * ```
 * <ng-container *ngComponentOutlet="componentTypeExpression;
 *                                   injector: injectorExpression;
 *                                   content: contentNodesExpression;">
 * </ng-container>
 * ```
 *
 * Customized ngModuleFactory
 * ```
 * <ng-container *ngComponentOutlet="componentTypeExpression;
 *                                   ngModuleFactory: moduleFactory;">
 * </ng-container>
 * ```
 *
 * ### A simple example
 *
 * {@example common/ngComponentOutlet/ts/module.ts region='SimpleExample'}

 * In this form, the template to be rendered for each iteration is the content
 * of an anchor element containing the directive.
 *
 * The following example shows the shorthand syntax with some options,
 * contained in an `<li>` element.
 *
 * ```
 * <li *ngFor="let item of items; index as i; trackBy: trackByFn">...</li>
 * ```
 *
 * The shorthand form expands into a long form that uses the `ngForOf` selector
 * on an `<ng-template>` element.
 * The content of the `<ng-template>` element is the `<li>` element that held the
 * short-form directive.
 *
 * Here is the expanded version of the short-form example.
 *
 * ```
 * <ng-template ngFor let-item [ngForOf]="items" let-i="index" [ngForTrackBy]="trackByFn">
 *   <li>...</li>
 * </ng-template>
 * ```
 *
 * Angular automatically expands the shorthand syntax as it compiles the template.
 * The context for each embedded view is logically merged to the current component
 * context according to its lexical position.
 *
 * When using the shorthand syntax, Angular allows only [one structural directive
 * on an element](guide/built-in-directives#one-per-element).
 * If you want to iterate conditionally, for example,
 * put the `*ngIf` on a container element that wraps the `*ngFor` element.
 * For futher discussion, see
 * [Structural Directives](guide/built-in-directives#one-per-element).
 *
 * @usageNotes
 *
 * ### Local variables
 *
 * `NgForOf` provides exported values that can be aliased to local variables.
 * For example:
 *
 *  ```
 * <li *ngFor="let user of users; index as i; first as isFirst">
 *    {{i}}/{{users.length}}. {{user}} <span *ngIf="isFirst">default</span>
 * </li>
 * ```
 *
 * The following exported values can be aliased to local variables:
 *
 * - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).
 * - `ngForOf: NgIterable<T>`: The value of the iterable expression. Useful when the expression is
 * more complex then a property access, for example when using the async pipe (`userStreams |
 * async`).
 * - `index: number`: The index of the current item in the iterable.
 * - `count: number`: The length of the iterable.
 * - `first: boolean`: True when the item is the first item in the iterable.
 * - `last: boolean`: True when the item is the last item in the iterable.
 * - `even: boolean`: True when the item has an even index in the iterable.
 * - `odd: boolean`: True when the item has an odd index in the iterable.
 *
 * ### Change propagation
 *
 * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:
 *
 * * When an item is added, a new instance of the template is added to the DOM.
 * * When an item is removed, its template instance is removed from the DOM.
 * * When items are reordered, their respective templates are reordered in the DOM.
 *
 * Angular uses object identity to track insertions and deletions within the iterator and reproduce
 * those changes in the DOM. This has important implications for animations and any stateful
 * controls that are present, such as `<input>` elements that accept user input. Inserted rows can
 * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state
 * such as user input.
 * For more on animations, see [Transitions and Triggers](guide/transition-and-triggers).
 *
 * The identities of elements in the iterator can change while the data does not.
 * This can happen, for example, if the iterator is produced from an RPC to the server, and that
 * RPC is re-run. Even if the data hasn't changed, the second response produces objects with
 * different identities, and Angular must tear down the entire DOM and rebuild it (as if all old
 * elements were deleted and all new elements inserted).
 *
 * To avoid this expensive operation, you can customize the default tracking algorithm.
 * by supplying the `trackBy` option to `NgForOf`.
 * `trackBy` takes a function that has two arguments: `index` and `item`.
 * If `trackBy` is given, Angular tracks changes by the return value of the function.

/**
 * A structural directive that conditionally includes a template based on the value of
 * an expression coerced to Boolean.
 * When the expression evaluates to true, Angular renders the template
 * provided in a `then` clause, and when  false or null,
 * Angular renders the template provided in an optional `else` clause. The default
 * template for the `else` clause is blank.
 *
 * A [shorthand form](guide/structural-directives#asterisk) of the directive,
 * `*ngIf="condition"`, is generally used, provided
 * as an attribute of the anchor element for the inserted template.
 * Angular expands this into a more explicit version, in which the anchor element
 * is contained in an `<ng-template>` element.
 *
 * Simple form with shorthand syntax:
 *
 * ```
 * <div *ngIf="condition">Content to render when condition is true.</div>
 * ```
 *
 * Simple form with expanded syntax:
 *
 * ```
 * <ng-template [ngIf]="condition"><div>Content to render when condition is
 * true.</div></ng-template>
 * ```
 *
 * Form with an "else" block:
 *
 * ```
 * <div *ngIf="condition; else elseBlock">Content to render when condition is true.</div>
 * <ng-template #elseBlock>Content to render when condition is false.</ng-template>
 * ```
 *
 * Shorthand form with "then" and "else" blocks:
 *
 * ```
 * <div *ngIf="condition; then thenBlock else elseBlock"></div>
 * <ng-template #thenBlock>Content to render when condition is true.</ng-template>
 * <ng-template #elseBlock>Content to render when condition is false.</ng-template>
 * ```
 *
 * Form with storing the value locally:
 *
 * ```
 * <div *ngIf="condition as value; else elseBlock">{{value}}</div>
 * <ng-template #elseBlock>Content to render when value is null.</ng-template>
 * ```
 *
 * @usageNotes
 *
 * The `*ngIf` directive is most commonly used to conditionally show an inline template,
 * as seen in the following  example.
 * The default `else` template is blank.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfSimple'}
 *
 * ### Showing an alternative template using `else`
 *
 * To display a template when `expression` evaluates to false, use an `else` template
 * binding as shown in the following example.
 * The `else` binding points to an `<ng-template>`  element labeled `#elseBlock`.
 * The template can be defined anywhere in the component view, but is typically placed right after
 * `ngIf` for readability.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfElse'}
 *
 * ### Using an external `then` template
 *
 * In the previous example, the then-clause template is specified inline, as the content of the
 * tag that contains the `ngIf` directive. You can also specify a template that is defined
 * externally, by referencing a labeled `<ng-template>` element. When you do this, you can
 * change which template to use at runtime, as shown in the following example.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfThenElse'}
 *
 * ### Storing a conditional result in a variable
 *
 * You might want to show a set of properties from the same object. If you are waiting
 * for asynchronous data, the object can be undefined.
 * In this case, you can use `ngIf` and store the result of the condition in a local
 * variable as shown in the following example.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfAs'}
 *
 * This code uses only one `AsyncPipe`, so only one subscription is created.
 * The conditional statement stores the result of `userStream|async` in the local variable `user`.
 * You can then bind the local `user` repeatedly.
 *
 * The conditional displays the data only if `userStream` returns a value,
 * so you don't need to use the
 * safe-navigation-operator (`?.`)
 * to guard against null values when accessing properties.
 * You can display an alternative template while waiting for the data.
 *
 * ### Shorthand syntax
 *
 * The shorthand syntax `*ngIf` expands into two separate template specifications
 * for the "then" and "else" clauses. For example, consider the following shorthand statement,
 * that is meant to show a loading page while waiting for data to be loaded.
 *
 * ```
 * <div class="hero-list" *ngIf="heroes else loading">
 *  ...
 * </div>
 *
 * <ng-template #loading>
 *  <div>Loading...</div>
 * </ng-template>
 * ```
 *
 * You can see that the "else" clause references the `<ng-template>`
 * with the `#loading` label, and the template for the "then" clause
 * is provided as the content of the anchor element.
 *
 * However, when Angular expands the shorthand syntax, it creates
 * another `<ng-template>` tag, with `ngIf` and `ngIfElse` directives.
 * The anchor element containing the template for the "then" clause becomes
 * the content of this unlabeled `<ng-template>` tag.
 *
 * ```
 * <ng-template [ngIf]="heroes" [ngIfElse]="loading">
 *  <div class="hero-list">
 *   ...
 *  </div>
 * </ng-template>
 *
 * <ng-template #loading>
 *  <div>Loading...</div>
 * </ng-template>
 * ```
 *
 * The presence of the implicit template object has implications for the nesting of
 * structural directives. For more on this subject, see
 * [Structural Directives](https://angular.io/guide/built-in-directives#one-per-element).

/**
 * @ngModule CommonModule
 *
 * @description
 * The `[ngSwitch]` directive on a container specifies an expression to match against.
 * The expressions to match are provided by `ngSwitchCase` directives on views within the container.
 * - Every view that matches is rendered.
 * - If there are no matches, a view with the `ngSwitchDefault` directive is rendered.
 * - Elements within the `[NgSwitch]` statement but outside of any `NgSwitchCase`
 * or `ngSwitchDefault` directive are preserved at the location.
 *
 * @usageNotes
 * Define a container element for the directive, and specify the switch expression
 * to match against as an attribute:
 *
 * ```
 * <container-element [ngSwitch]="switch_expression">
 * ```
 *
 * Within the container, `*ngSwitchCase` statements specify the match expressions
 * as attributes. Include `*ngSwitchDefault` as the final case.
 *
 * ```
 * <container-element [ngSwitch]="switch_expression">
 *    <some-element *ngSwitchCase="match_expression_1">...</some-element>
 * ...
 *    <some-element *ngSwitchDefault>...</some-element>
 * </container-element>
 * ```
 *
 * ### Usage Examples
 *
 * The following example shows how to use more than one case to display the same view:
 *
 * ```
 * <container-element [ngSwitch]="switch_expression">
 *   <!-- the same view can be shown in more than one case -->
 *   <some-element *ngSwitchCase="match_expression_1">...</some-element>
 *   <some-element *ngSwitchCase="match_expression_2">...</some-element>
 *   <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
 *   <!--default case when there are no matches -->
 *   <some-element *ngSwitchDefault>...</some-element>
 * </container-element>
 * ```
 *
 * The following example shows how cases can be nested:
 * ```
 * <container-element [ngSwitch]="switch_expression">
 *       <some-element *ngSwitchCase="match_expression_1">...</some-element>
 *       <some-element *ngSwitchCase="match_expression_2">...</some-element>
 *       <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
 *       <ng-container *ngSwitchCase="match_expression_3">
 *         <!-- use a ng-container to group multiple root nodes -->
 *         <inner-element></inner-element>
 *         <inner-other-element></inner-other-element>
 *       </ng-container>
 *       <some-element *ngSwitchDefault>...</some-element>
 *     </container-element>
 * ```

 * @description
 *
 * Unwraps a value from an asynchronous primitive.
 *
 * The `async` pipe subscribes to an `Observable` or `Promise` and returns the latest value it has
 * emitted. When a new value is emitted, the `async` pipe marks the component to be checked for
 * changes. When the component gets destroyed, the `async` pipe unsubscribes automatically to avoid
 * potential memory leaks. When the reference of the expression changes, the `async` pipe
 * automatically unsubscribes from the old `Observable` or `Promise` and subscribes to the new one.
 *
 * @usageNotes
 *
 * ### Examples
 *
 * This example binds a `Promise` to the view. Clicking the `Resolve` button resolves the
 * promise.
 *
 * {@example common/pipes/ts/async_pipe.ts region='AsyncPipePromise'}
 *
 * It's also possible to use `async` with Observables. The example below binds the `time` Observable
 * to the view. The Observable continuously updates the view with the current time.
 *
 * {@example common/pipes/ts/async_pipe.ts region='AsyncPipeObservable'}

/**

 * @description
 *
 * Formats a date value according to locale rules.
 *
 * `DatePipe` is executed only when it detects a pure change to the input value.
 * A pure change is either a change to a primitive input value
 * (such as `String`, `Number`, `Boolean`, or `Symbol`),
 * or a changed object reference (such as `Date`, `Array`, `Function`, or `Object`).
 *
 * Note that mutating a `Date` object does not cause the pipe to be rendered again.
 * To ensure that the pipe is executed, you must create a new `Date` object.
 *
 * Only the `en-US` locale data comes with Angular. To localize dates
 * in another language, you must import the corresponding locale data.
 * See the [I18n guide](guide/i18n-common-format-data-locale) for more information.
 *
 * @see `formatDate()`
 *
 *
 * @usageNotes
 *
 * The result of this pipe is not reevaluated when the input is mutated. To avoid the need to
 * reformat the date on every change-detection cycle, treat the date as an immutable object
 * and change the reference when the pipe needs to run again.
 *
 * ### Pre-defined format options

 * ### Format examples
 *
 * These examples transform a date into various formats,
 * assuming that `dateObj` is a JavaScript `Date` object for
 * year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,
 * given in the local time for the `en-US` locale.
 *
 * ```
 * {{ dateObj | date }}               // output is 'Jun 15, 2015'
 * {{ dateObj | date:'medium' }}      // output is 'Jun 15, 2015, 9:43:11 PM'
 * {{ dateObj | date:'shortTime' }}   // output is '9:43 PM'
 * {{ dateObj | date:'mm:ss' }}       // output is '43:11'
 * ```
 *
 * ### Usage example
 *
 * The following component uses a date pipe to display the current date in different formats.
 *
 * ```
 * @Component({
 *  selector: 'date-pipe',
 *  template: `<div>
 *    <p>Today is {{today | date}}</p>
 *    <p>Or if you prefer, {{today | date:'fullDate'}}</p>
 *    <p>The time is {{today | date:'h:mm a z'}}</p>
 *  </div>`
 * })
 * // Get the current date and time as a date-time value.
 * export class DatePipeComponent {
 *   today: number = Date.now();
 * }
 * ```

 *
 * ### digitsInfo
 *
 * The value's decimal representation is specified by the `digitsInfo`

 *
 * ```
 * {minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}
 * ```
 *
 *  - `minIntegerDigits`:

 * The minimum number of digits after the decimal point.
 * Default is 0.
 *
 *  - `maxFractionDigits`:
 * The maximum number of digits after the decimal point.
 * Default is 3.
 *
 * If the formatted value is truncated it will be rounded using the "to-nearest" method:

 * {{3.6 | number: '1.0-0'}}
 * <!--will output '4'-->
 *
 * {{-3.6 | number:'1.0-0'}}

 *
 * ### locale
 *
 * `locale` will format a value according to locale rules.
 * Locale determines group sizing and separator,
 * decimal point character, and other locale-specific configurations.
 *
 * When not supplied, uses the value of `LOCALE_ID`, which is `en-US` by default.
 *
 * See [Setting your app locale](guide/i18n-common-locale-id).

 * The default currency code is currently always `USD` but this is deprecated from v9.
 *
 * **In v11 the default currency code will be taken from the current locale identified by
 * the `LOCALE_ID` token. See the [i18n guide](guide/i18n-common-locale-id) for
 * more information.**
 *
 * If you need the previous behavior then set it by creating a `DEFAULT_CURRENCY_CODE` provider in
 * your application `NgModule`:
 *
 * ```ts
 * {provide: DEFAULT_CURRENCY_CODE, useValue: 'USD'}
 * ```
 *

     * @param currencyCode The [ISO 4217](https://en.wikipedia.org/wiki/ISO_4217) currency code,
     * such as `USD` for the US dollar and `EUR` for the euro. The default currency code can be
     * configured using the `DEFAULT_CURRENCY_CODE` injection token.
     * @param display The format for the currency indicator. One of the following:
     *   - `code`: Show the code (such as `USD`).
     *   - `symbol`(default): Show the symbol (such as `$`).
     *   - `symbol-narrow`: Use the narrow symbol for locales that have two symbols for their
     * currency.
     * For example, the Canadian dollar CAD has the symbol `CA$` and the symbol-narrow `$`. If the
     * locale has no narrow symbol, uses the standard symbol for the locale.
     *   - String: Use the given string value instead of a code or a symbol.
     * For example, an empty string will suppress the currency & symbol.
     *   - Boolean (marked deprecated in v5): `true` for symbol and false for `code`.
     *
     * @param digitsInfo Decimal representation options, specified by a string
     * in the following format:<br>
     * <code>{minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}</code>.
     *   - `minIntegerDigits`: The minimum number of integer digits before the decimal point.
     * Default is `1`.
     *   - `minFractionDigits`: The minimum number of digits after the decimal point.
     * Default is `2`.
     *   - `maxFractionDigits`: The maximum number of digits after the decimal point.
     * Default is `2`.
     * If not provided, the number will be formatted with the proper amount of digits,
     * depending on what the [ISO 4217](https://en.wikipedia.org/wiki/ISO_4217) specifies.
     * For example, the Canadian dollar has 2 digits, whereas the Chilean peso has none.
     * @param locale A locale code for the locale format rules to use.
     * When not supplied, uses the value of `LOCALE_ID`, which is `en-US` by default.
     * See [Setting your app locale](guide/i18n-common-locale-id).

 *
 * @usageNotes
 * Sample HTTP requests for the [Tour of Heroes](/tutorial/toh-pt0) application.
 *
 * ### HTTP Request Example
 *
 * ```
 *  // GET heroes whose name contains search term
 * searchHeroes(term: string): observable<Hero[]>{
 *
 *  const params = new HttpParams({fromString: 'name=term'});
 *    return this.httpClient.request('GET', this.heroesUrl, {responseType:'json', params});
 * }
 * ```
 *
 * Alternatively, the parameter string can be used without invoking HttpParams
 * by directly joining to the URL.
 * ```
 * this.httpClient.request('GET', this.heroesUrl + '?' + 'name=term', {responseType:'json'});
 * ```
 *
 *
 * ### JSONP Example
 * ```
 * requestJsonp(url, callback = 'callback') {
 *  return this.httpClient.jsonp(this.heroesURL, callback);
 * }
 * ```
 *
 * ### PATCH Example
 * ```
 * // PATCH one of the heroes' name
 * patchHero (id: number, heroName: string): Observable<{}> {
 * const url = `${this.heroesUrl}/${id}`;   // PATCH api/heroes/42
 *  return this.httpClient.patch(url, {name: heroName}, httpOptions)
 *    .pipe(catchError(this.handleError('patchHero')));
 * }

/*
  This is a limited shim for ShadowDOM css styling.
  https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html#styles

  The intention here is to support only the styling features which can be
  relatively simply implemented. The goal is to allow users to avoid the
  most obvious pitfalls and do so without compromising performance significantly.
  For ShadowDOM styling that's not covered here, a set of best practices
  can be provided that should allow users to accomplish more complex styling.

  The following is a list of specific ShadowDOM styling features and a brief
  discussion of the approach used to shim.

  Shimmed features:

  * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host
  element using the :host rule. To shim this feature, the :host styles are
  reformatted and prefixed with a given scope name and promoted to a
  document level stylesheet.
  For example, given a scope name of .foo, a rule like this:

    :host {
        background: red;
      }
    }

  becomes:

    .foo {
      background: red;
    }

  * encapsulation: Styles defined within ShadowDOM, apply only to
  dom inside the ShadowDOM. Polymer uses one of two techniques to implement
  this feature.

  By default, rules are prefixed with the host element tag name
  as a descendant selector. This ensures styling does not leak out of the 'top'
  of the element's ShadowDOM. For example,

  div {
      font-weight: bold;
    }

  becomes:

  x-foo div {
      font-weight: bold;
    }

  becomes:


  Alternatively, if WebComponents.ShadowCSS.strictStyling is set to true then
  selectors are scoped by adding an attribute selector suffix to each
  simple selector that contains the host element tag name. Each element
  in the element's ShadowDOM template is also given the scope attribute.
  Thus, these rules match only elements that have the scope attribute.
  For example, given a scope name of x-foo, a rule like this:

    div {
      font-weight: bold;
    }

  becomes:

    div[x-foo] {
      font-weight: bold;
    }

  Note that elements that are dynamically added to a scope must have the scope
  selector added to them manually.

  * upper/lower bound encapsulation: Styles which are defined outside a
  shadowRoot should not cross the ShadowDOM boundary and should not apply
  inside a shadowRoot.

  This styling behavior is not emulated. Some possible ways to do this that
  were rejected due to complexity and/or performance concerns include: (1) reset
  every possible property for every possible selector for a given scope name;
  (2) re-implement css in javascript.

  As an alternative, users should make sure to use selectors
  specific to the scope in which they are working.

  * ::distributed: This behavior is not emulated. It's often not necessary
  to style the contents of a specific insertion point and instead, descendants
  of the host element can be styled selectively. Users can also create an
  extra node around an insertion point and style that node's contents
  via descendent selectors. For example, with a shadowRoot like this:

    <style>
      ::content(div) {
        background: red;
      }
    </style>
    <content></content>

  could become:

    <style>
      / *@polyfill .content-container div * /
      ::content(div) {
        background: red;
      }
    </style>
    <div class="content-container">
      <content></content>
    </div>

  Note the use of @polyfill in the comment above a ShadowDOM specific style
  declaration. This is a directive to the styling shim to use the selector
  in comments in lieu of the next selector when running under polyfill.

     * `@font-face` rules cannot contain nested selectors. Nor can they be nested under a selector.

     * can end up with broken css if the imported styles happen to contain @font-face rules.

     * :host ::ng-deep {

/**
 * Minimum amount of binding slots required in the runtime for style/class bindings.
 *
 * Styling in Angular uses up two slots in the runtime LView/TData data structures to
 * record binding data, property information and metadata.
 *
 * When a binding is registered it will place the following information in the `LView`:
 *
 * slot 1) binding value
 * slot 2) cached value (all other values collected before it in string form)
 *
 * When a binding is registered it will place the following information in the `TData`:
 *
 * slot 1) prop name
 * slot 2) binding index that points to the previous style/class binding (and some extra config
 * values)
 *
 * Let's imagine we have a binding that looks like so:
 *
 * ```
 * <div [style.width]="x" [style.height]="y">
 * ```
 *
 * Our `LView` and `TData` data-structures look like so:
 *
 * ```typescript
 * LView = [
 *   // ...
 *   x, // value of x
 *   "width: x",
 *
 *   y, // value of y
 *   "width: x; height: y",
 *   // ...
 * ];
 *
 * TData = [
 *   // ...
 *   "width", // binding slot 20
 *   0,
 *
 *   "height",
 *   20,
 *   // ...
 * ];
 * ```

 * - Static style/class attributes (style="..." and class="...")
 * - Dynamic style/class map bindings ([style]="map" and [class]="map|string")

/**
 * This array represents the DOM schema. It encodes inheritance, properties, and events.
 *
 * ## Overview
 *
 * Each line represents one kind of element. The `element_inheritance` and properties are joined
 * using `element_inheritance|properties` syntax.
 *
 * ## Element Inheritance
 *
 * The `element_inheritance` can be further subdivided as `element1,element2,...^parentElement`.
 * Here the individual elements are separated by `,` (commas). Every element in the list
 * has identical properties.
 *
 * An `element` may inherit additional properties from `parentElement` If no `^parentElement` is
 * specified then `""` (blank) element is assumed.
 *
 * NOTE: The blank element inherits from root `[Element]` element, the super element of all
 * elements.
 *
 * NOTE an element prefix such as `:svg:` has no special meaning to the schema.
 *
 * ## Properties
 *
 * Each element has a set of properties separated by `,` (commas). Each property can be prefixed
 * by a special character designating its type:
 *
 * - (no prefix): property is a string.
 * - `*`: property represents an event.
 * - `!`: property is a boolean.
 * - `#`: property is a number.
 * - `%`: property is an object.
 *
 * ## Query
 *
 * The class creates an internal squas representation which allows to easily answer the query of
 * if a given property exist on a given element.
 *
 * NOTE: We don't yet support querying for types or events.
 * NOTE: This schema is auto extracted from `schema_extractor.ts` located in the test folder,
 *       see dom_element_schema_registry_spec.ts

/**
 * A regular expression for breaking a URI into its component parts.
 *
 * {@link https://tools.ietf.org/html/rfc3986#appendix-B} says
 * As the "first-match-wins" algorithm is identical to the "greedy"
 * disambiguation method used by POSIX regular expressions, it is natural and
 * commonplace to use a regular expression for parsing the potential five
 * components of a URI reference.
 *
 * The following line is the regular expression for breaking-down a
 * well-formed URI reference into its components.
 *
 * <pre>
 * ^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?
 *  12            3  4          5       6  7        8 9
 * </pre>
 *
 * The numbers in the second line above are only to assist readability; they
 * indicate the reference points for each subexpression (i.e., each paired
 * parenthesis). We refer to the value matched for subexpression <n> as $<n>.
 * For example, matching the above expression to
 * <pre>
 *     http://www.ics.uci.edu/pub/ietf/uri/#Related
 * </pre>
 * results in the following subexpression matches:
 * <pre>
 *    $1 = http:
 *    $2 = http
 *    $3 = //www.ics.uci.edu
 *    $4 = www.ics.uci.edu
 *    $5 = /pub/ietf/uri/
 *    $6 = <undefined>
 *    $7 = <undefined>
 *    $8 = #Related
 *    $9 = Related
 * </pre>
 * where <undefined> indicates that the component is not present, as is the
 * case for the query component in the above example. Therefore, we can
 * determine the value of the five components as
 * <pre>
 *    scheme    = $2
 *    authority = $4
 *    path      = $5
 *    query     = $7
 *    fragment  = $9
 * </pre>
 *
 * The regular expression has been modified slightly to expose the
 * userInfo, domain, and port separately from the authority.
 * The modified version yields
 * <pre>
 *    $1 = http              scheme
 *    $2 = <undefined>       userInfo -\
 *    $3 = www.ics.uci.edu   domain     | authority
 *    $4 = <undefined>       port     -/
 *    $5 = /pub/ietf/uri/    path
 *    $6 = <undefined>       query without ?
 *    $7 = Related           fragment without #
 * </pre>
 * @internal

/**
 * Creates a token that can be used in a DI Provider.
 *
 * Use an `InjectionToken` whenever the type you are injecting is not reified (does not have a
 * runtime representation) such as when injecting an interface, callable type, array or
 * parameterized type.
 *
 * `InjectionToken` is parameterized on `T` which is the type of object which will be returned by
 * the `Injector`. This provides an additional level of type safety.
 *
 * ```
 * interface MyInterface {...}
 * const myInterface = injector.get(new InjectionToken<MyInterface>('SomeToken'));
 * // myInterface is inferred to be MyInterface.
 * ```
 *
 * When creating an `InjectionToken`, you can optionally specify a factory function which returns
 * (possibly by creating) a default value of the parameterized type `T`. This sets up the
 * `InjectionToken` using this factory as a provider as if it was defined explicitly in the
 * application's root injector. If the factory function, which takes zero arguments, needs to inject
 * dependencies, it can do so using the `inject` function.

 * regular expression matches if (comment from here on and regex copied from
 * Soy's EscapingConventions):
 * (1) Either an allowed protocol (http, https, mailto or ftp).
 * (2) or no protocol.  A protocol must be followed by a colon. The below

 *     A colon after a hash (#) must be in the fragment.
 *     Otherwise, a colon after a (?) must be in a query.
 *     Otherwise, a colon after a single solidus (/) must be in a path.
 *     Otherwise, a colon after a double solidus (//) must be in the authority
 *     (before port).
 *
 * The pattern disallows &, used in HTML entity declarations before
 * one of the characters in [/?#]. This disallows HTML entities used in the
 * protocol name, which should never happen, e.g. "h&#116;tp" for "http".
 * It also disallows HTML entities in the first path part of a relative path,
 * e.g. "foo&lt;bar/baz".  Our existing escaping functions should not produce

 * monkey-patched property to derive the `LContext` data. Once called then the monkey-patched
 * value will be that of the newly created `LContext`.
 *
 * If the monkey-patched value is the `LView` instance then the context value for that
 * target will be created and the monkey-patch reference will be updated. Therefore when this
 * function is called it may mutate the provided element\'s, component\'s or any of the associated
 * directive\'s monkey-patch values.
 *
 * If the monkey-patch value is not detected then the code will walk up the DOM until an element
 * is found which contains a monkey-patch reference. When that occurs then the provided element
 * will be updated with a new context (which is then returned). If the monkey-patch value is not
 * detected for a component/directive instance then it will throw an error (all components and
 * directives should be automatically monkey-patched by ivy).
 *
 * @param target Component, Directive or DOM Node.

/**
 * A ReflectiveDependency injection container used for instantiating objects and resolving
 * dependencies.
 *
 * An `Injector` is a replacement for a `new` operator, which can automatically resolve the
 * constructor dependencies.
 *
 * In typical use, application code asks for the dependencies in the constructor and they are
 * resolved by the `Injector`.
 *
 * @usageNotes
 * ### Example
 *
 * The following example creates an `Injector` configured to create `Engine` and `Car`.
 *
 * ```typescript
 * @Injectable()
 * class Engine {
 * }
 *
 * @Injectable()
 * class Car {
 *   constructor(public engine:Engine) {}
 * }
 *
 * var injector = ReflectiveInjector.resolveAndCreate([Car, Engine]);
 * var car = injector.get(Car);
 * expect(car instanceof Car).toBe(true);
 * expect(car.engine instanceof Engine).toBe(true);
 * ```
 *
 * Notice, we don't use the `new` operator because we explicitly want to have the `Injector`
 * resolve all of the object's dependencies automatically.
 *
 * @deprecated from v5 - slow and brings in a lot of code, Use `Injector.create` instead.

/**
 * NOTE: The word `styling` is used interchangeably as style or class styling.
 *
 * This file contains code to link styling instructions together so that they can be replayed in
 * priority order. The file exists because Ivy styling instruction execution order does not match
 * that of the priority order. The purpose of this code is to create a linked list so that the
 * instructions can be traversed in priority order when computing the styles.
 *
 * Assume we are dealing with the following code:
 * ```
 * @Component({
 *   template: `
 *     <my-cmp [style]=" {color: '#001'} "
 *             [style.color]=" #002 "
 *             dir-style-color-1
 *             dir-style-color-2> `
 * })
 * class ExampleComponent {
 *   static ngComp = ... {
 *     ...
 *     // Compiler ensures that `ɵɵstyleProp` is after `ɵɵstyleMap`
 *     ɵɵstyleMap({color: '#001'});
 *     ɵɵstyleProp('color', '#002');
 *     ...
 *   }
 * }
 *
 * @Directive({
 *   selector: `[dir-style-color-1]',
 * })
 * class Style1Directive {
 *   @HostBinding('style') style = {color: '#005'};

 *
 *   static ngDir = ... {
 *     ...
 *     // Compiler ensures that `ɵɵstyleProp` is after `ɵɵstyleMap`
 *     ɵɵstyleMap({color: '#005'});
 *     ɵɵstyleProp('color', '#006');
 *     ...
 *   }
 * }
 *
 * @Directive({
 *   selector: `[dir-style-color-2]',
 * })
 * class Style2Directive {
 *   @HostBinding('style') style = {color: '#007'};
 *   @HostBinding('style.color') color = '#008';
 *
 *   static ngDir = ... {
 *     ...
 *     // Compiler ensures that `ɵɵstyleProp` is after `ɵɵstyleMap`
 *     ɵɵstyleMap({color: '#007'});
 *     ɵɵstyleProp('color', '#008');
 *     ...
 *   }
 * }
 *
 * @Directive({
 *   selector: `my-cmp',
 * })
 * class MyComponent {
 *   @HostBinding('style') style = {color: '#003'};
 *   @HostBinding('style.color') color = '#004';
 *
 *   static ngComp = ... {
 *     ...
 *     // Compiler ensures that `ɵɵstyleProp` is after `ɵɵstyleMap`
 *     ɵɵstyleMap({color: '#003'});
 *     ɵɵstyleProp('color', '#004');
 *     ...
 *   }
 * }
 * ```
 *
 * The Order of instruction execution is:
 *
 * NOTE: the comment binding location is for illustrative purposes only.
 *
 * ```
 * // Template: (ExampleComponent)
 *     ɵɵstyleMap({color: '#001'});   // Binding index: 10
 *     ɵɵstyleProp('color', '#002');  // Binding index: 12
 * // MyComponent
 *     ɵɵstyleMap({color: '#003'});   // Binding index: 20
 *     ɵɵstyleProp('color', '#004');  // Binding index: 22
 * // Style1Directive
 *     ɵɵstyleMap({color: '#005'});   // Binding index: 24
 *     ɵɵstyleProp('color', '#006');  // Binding index: 26
 * // Style2Directive
 *     ɵɵstyleMap({color: '#007'});   // Binding index: 28
 *     ɵɵstyleProp('color', '#008');  // Binding index: 30
 * ```
 *
 * The correct priority order of concatenation is:
 *
 * ```
 * // MyComponent
 *     ɵɵstyleMap({color: '#003'});   // Binding index: 20
 *     ɵɵstyleProp('color', '#004');  // Binding index: 22
 * // Style1Directive
 *     ɵɵstyleMap({color: '#005'});   // Binding index: 24
 *     ɵɵstyleProp('color', '#006');  // Binding index: 26
 * // Style2Directive
 *     ɵɵstyleMap({color: '#007'});   // Binding index: 28
 *     ɵɵstyleProp('color', '#008');  // Binding index: 30
 * // Template: (ExampleComponent)
 *     ɵɵstyleMap({color: '#001'});   // Binding index: 10
 *     ɵɵstyleProp('color', '#002');  // Binding index: 12
 * ```
 *
 * What color should be rendered?
 *
 * Once the items are correctly sorted in the list, the answer is simply the last item in the
 * concatenation list which is `#002`.
 *
 * To do so we keep a linked list of all of the bindings which pertain to this element.
 * Notice that the bindings are inserted in the order of execution, but the `TView.data` allows
 * us to traverse them in the order of priority.
 *
 * |Idx|`TView.data`|`LView`          | Notes
 * |---|------------|-----------------|--------------
 * |...|            |                 |

 * |21 |`0 | 22`    | ...             |
 * |22 |`color`     |`'#004'`         | `ɵɵstyleProp('color', '#004')`
 * |23 |`20 | 24`   | ...             |
 * |24 |`null`      |`{color: '#005'}`| `ɵɵstyleMap('color', {color: '#005'})`
 * |25 |`22 | 26`   | ...             |
 * |26 |`color`     |`'#006'`         | `ɵɵstyleProp('color', '#006')`
 * |27 |`24 | 28`   | ...             |
 * |28 |`null`      |`{color: '#007'}`| `ɵɵstyleMap('color', {color: '#007'})`

 * |31 |`28 | 10`   | ...             |
 *
 * The above data structure allows us to re-concatenate the styling no matter which data binding
 * changes.
 *
 * NOTE: in addition to keeping track of next/previous index the `TView.data` also stores prev/next
 * duplicate bit. The duplicate bit if true says there either is a binding with the same name or
 * there is a map (which may contain the name). This information is useful in knowing if other
 * styles with higher priority need to be searched for overwrites.
 *
 * NOTE: See `should support example in 'tnode_linked_list.ts' documentation` in
 * `tnode_linked_list_spec.ts` for working example.

 * ```

 * ```
 *  ['', 'color', 'color', 'red', 'width', '100px'],

 *

 * instructions and must assume that there are none and must collect all of the static styling.

 * When `'[style.color]': 'dirExp',` executes we need to insert a new data into the linked list.

 *  ['', 'color', 'color', 'red', 'width', '100px'], // this is wrong

 *    `ɵɵi18nStart` instruction.
 * 2. All `TNodeType.Placeholder` `TNodes` are elements which will be created later by

 * We use the above three invariants to determine `TNode.insertBeforeIndex`.
 *
 * In an ideal world `TNode.insertBeforeIndex` would always be `TNode.next.index`. However,
 * this will not work because `TNode.next.index` may be larger than `TNode.index` which means that
 * the next node is not yet created and therefore we can't insert in front of it.

 * The following examples demonstrate how to modify default change-detection behavior
 * to perform explicit detection when needed.
 *
 * ### Use `markForCheck()` with `CheckOnce` strategy
 *
 * The following example sets the `OnPush` change-detection strategy for a component
 * (`CheckOnce`, rather than the default `CheckAlways`), then forces a second check
 * after an interval. See [live demo](https://plnkr.co/edit/GC512b?p=preview).
 *
 * <code-example path="core/ts/change_detect/change-detection.ts"
 * region="mark-for-check"></code-example>
 *
 * ### Detach change detector to limit how often check occurs
 *
 * The following example defines a component with a large list of read-only data
 * that is expected to change constantly, many times per second.
 * To improve performance, we want to check and update the list
 * less often than the changes actually occur. To do that, we detach
 * the component's change detector and perform an explicit local check every five seconds.
 *
 * <code-example path="core/ts/change_detect/change-detection.ts" region="detach"></code-example>
 *
 *
 * ### Reattaching a detached component
 *
 * The following example creates a component displaying live data.
 * The component detaches its change detector from the main change detector tree
 * when the `live` property is set to false, and reattaches it when the property
 * becomes true.

// This function calls the ngAfterContentCheck, ngAfterContentInit,
// ngAfterViewCheck, and ngAfterViewInit lifecycle hooks (depending on the node
// flags in lifecycle). Unlike ngDoCheck, ngOnChanges and ngOnInit, which are
// called during a pre-order traversal of the view tree (that is calling the
// parent hooks before the child hooks) these events are sent in using a
// post-order traversal of the tree (children before parents). This changes the
// meaning of initIndex in the view state. For ngOnInit, initIndex tracks the
// expected nodeIndex which a ngOnInit should be called. When sending
// ngAfterContentInit and ngAfterViewInit it is the expected count of
// ngAfterContentInit or ngAfterViewInit methods that have been called. This
// ensure that despite being called recursively or after picking up after an
// exception, the ngAfterContentInit or ngAfterViewInit will be called on the
// correct nodes. Consider for example, the following (where E is an element
// and D is a directive)
//  Tree:       pre-order index  post-order index
//    E1        0                6
//      E2      1                1
//       D3     2                0
//      E4      3                5
//       E5     4                4
//        E6    5                2
//        E7    6                3
// As can be seen, the post-order index has an unclear relationship to the
// pre-order index (postOrderIndex === preOrderIndex - parentCount +
// childCount). Since number of calls to ngAfterContentInit and ngAfterViewInit
// are stable (will be the same for the same view regardless of exceptions or
// recursion) we just need to count them which will roughly correspond to the
// post-order index (it skips elements and directives that do not have
// lifecycle hooks).
//
// For example, if an exception is raised in the E6.onAfterViewInit() the
// initIndex is left at 3 (by shouldCallLifecycleInitHook() which set it to
// initIndex + 1). When checkAndUpdateView() is called again D3, E2 and E6 will
// not have their ngAfterViewInit() called but, starting with E7, the rest of
// the view will begin getting ngAfterViewInit() called until a check and
// pass is complete.
//
// This algorthim also handles recursion. Consider if E4's ngAfterViewInit()
// indirectly calls E1's ChangeDetectorRef.detectChanges(). The expected
// initIndex is set to 6, the recusive checkAndUpdateView() starts walk again.
// D3, E2, E6, E7, E5 and E4 are skipped, ngAfterViewInit() is called on E1.
// When the recursion returns the initIndex will be 7 so E1 is skipped as it
// has already been called in the recursively called checkAnUpdateView().

/**
 * A [DI token](guide/glossary#di-token "DI token definition") that you can use to provide
 * one or more initialization functions.
 *
 * The provided functions are injected at application startup and executed during
 * app initialization. If any of these functions returns a Promise or an Observable, initialization
 * does not complete until the Promise is resolved or the Observable is completed.
 *
 * You can, for example, create a factory function that loads language data
 * or an external configuration, and provide that function to the `APP_INITIALIZER` token.
 * The function is executed during the application bootstrap process,
 * and the needed data is available on startup.
 *
 * @see `ApplicationInitStatus`
 *
 * @usageNotes
 *
 * The following example illustrates how to configure a multi-provider using `APP_INITIALIZER` token
 * and a function returning a promise.
 *
 * ```
 *  function initializeApp(): Promise<any> {
 *    return new Promise((resolve, reject) => {
 *      // Do some asynchronous stuff
 *      resolve();
 *    });
 *  }
 *

 *   imports: [BrowserModule],

 *     provide: APP_INITIALIZER,
 *     useFactory: () => initializeApp,
 *     multi: true
 *    }]
 *   })
 *  export class AppModule {}
 * ```
 *
 * It's also possible to configure a multi-provider using `APP_INITIALIZER` token and a function
 * returning an observable, see an example below. Note: the `HttpClient` in this example is used for
 * demo purposes to illustrate how the factory function can work with other providers available
 * through DI.
 *
 * ```
 *  function initializeAppFactory(httpClient: HttpClient): () => Observable<any> {
 *   return () => httpClient.get("https://someUrl.com/api/user")
 *     .pipe(
 *        tap(user => { ... })
 *     );
 *  }
 *

/**
 * A reference to an Angular application running on a page.
 *
 * @usageNotes
 *
 * {@a is-stable-examples}
 * ### isStable examples and caveats
 *
 * Note two important points about `isStable`, demonstrated in the examples below:
 * - the application will never be stable if you start any kind
 * of recurrent asynchronous task when the application starts
 * (for example for a polling process, started with a `setInterval`, a `setTimeout`
 * or using RxJS operators like `interval`);
 * - the `isStable` Observable runs outside of the Angular zone.
 *
 * Let's imagine that you start a recurrent task
 * (here incrementing a counter, using RxJS `interval`),
 * and at the same time subscribe to `isStable`.
 *
 * ```
 * constructor(appRef: ApplicationRef) {
 *   appRef.isStable.pipe(
 *      filter(stable => stable)
 *   ).subscribe(() => console.log('App is stable now');
 *   interval(1000).subscribe(counter => console.log(counter));
 * }
 * ```
 * In this example, `isStable` will never emit `true`,
 * and the trace "App is stable now" will never get logged.
 *
 * If you want to execute something when the app is stable,
 * you have to wait for the application to be stable
 * before starting your polling process.
 *
 * ```
 * constructor(appRef: ApplicationRef) {
 *   appRef.isStable.pipe(
 *     first(stable => stable),
 *     tap(stable => console.log('App is stable now')),
 *     switchMap(() => interval(1000))
 *   ).subscribe(counter => console.log(counter));
 * }
 * ```
 * In this example, the trace "App is stable now" will be logged
 * and then the counter starts incrementing every second.
 *
 * Note also that this Observable runs outside of the Angular zone,
 * which means that the code in the subscription
 * to this Observable will not trigger the change detection.
 *
 * Let's imagine that instead of logging the counter value,
 * you update a field of your component
 * and display it in its template.
 *
 * ```
 * constructor(appRef: ApplicationRef) {
 *   appRef.isStable.pipe(
 *     first(stable => stable),
 *     switchMap(() => interval(1000))
 *   ).subscribe(counter => this.value = counter);
 * }
 * ```
 * As the `isStable` Observable runs outside the zone,
 * the `value` field will be updated properly,
 * but the template will not be refreshed!
 *
 * You'll have to manually trigger the change detection to update the template.
 *
 * ```
 * constructor(appRef: ApplicationRef, cd: ChangeDetectorRef) {
 *   appRef.isStable.pipe(
 *     first(stable => stable),
 *     switchMap(() => interval(1000))
 *   ).subscribe(counter => {
 *     this.value = counter;
 *     cd.detectChanges();
 *   });
 * }
 * ```
 *
 * Or make the subscription callback run inside the zone.
 *
 * ```
 * constructor(appRef: ApplicationRef, zone: NgZone) {
 *   appRef.isStable.pipe(
 *     first(stable => stable),
 *     switchMap(() => interval(1000))
 *   ).subscribe(counter => zone.run(() => this.value = counter));
 * }
 * ```

     * Bootstrap a component onto the element identified by its selector or, optionally, to a
     * specified element.
     *
     * @usageNotes
     * ### Bootstrap process
     *
     * When bootstrapping a component, Angular mounts it onto a target DOM element
     * and kicks off automatic change detection. The target DOM element can be
     * provided using the `rootSelectorOrNode` argument.
     *
     * If the target DOM element is not provided, Angular tries to find one on a page
     * using the `selector` of the component that is being bootstrapped
     * (first matched element is used).
     *
     * ### Example
     *
     * Generally, we define the component to bootstrap in the `bootstrap` array of `NgModule`,
     * but it requires us to know the component while writing the application code.
     *
     * Imagine a situation where we have to wait for an API call to decide about the component to
     * bootstrap. We can use the `ngDoBootstrap` hook of the `NgModule` and call this method to
     * dynamically bootstrap a component.
     *
     * {@example core/ts/platform/platform.ts region='componentSelector'}
     *
     * Optionally, a component can be mounted onto a DOM element that does not match the
     * selector of the bootstrapped component.
     *
     * In the following example, we are providing a CSS selector to match the target element.
     *
     * {@example core/ts/platform/platform.ts region='cssSelector'}
     *
     * While in this example, we are providing reference to a DOM node.
     *
     * {@example core/ts/platform/platform.ts region='domNode'}

 * The following template breaks down into two separate `TemplateRef` instances,
 * an outer one and an inner one.
 *
 * ```
 * Count: {{items.length}}
 * <ul>
 *   <li *ngFor="let  item of items">{{item}}</li>
 * </ul>
 * ```
 *
 * This is the outer `TemplateRef`:
 *
 * ```
 * Count: {{items.length}}
 * <ul>
 *   <ng-template ngFor let-item [ngForOf]="items"></ng-template>
 * </ul>
 * ```
 *
 * This is the inner `TemplateRef`:
 *
 * ```
 *   <li>{{item}}</li>
 * ```
 *
 * The outer and inner `TemplateRef` instances are assembled into views as follows:
 *
 * ```
 * <!-- ViewRef: outer-0 -->
 * Count: 2
 * <ul>
 *   <ng-template view-container-ref></ng-template>
 *   <!-- ViewRef: inner-1 --><li>first</li><!-- /ViewRef: inner-1 -->
 *   <!-- ViewRef: inner-2 --><li>second</li><!-- /ViewRef: inner-2 -->
 * </ul>
 * <!-- /ViewRef: outer-0 -->

 * At a high level, this regexp matches e-mail addresses of the format `local-part@tld`, where:
 * - `local-part` consists of one or more of the allowed characters (alphanumeric and some
 *   punctuation symbols).
 * - `local-part` cannot begin or end with a period (`.`).
 * - `local-part` cannot be longer than 64 characters.
 * - `tld` consists of one or more `labels` separated by periods (`.`). For example `localhost` or
 *   `foo.com`.
 * - A `label` consists of one or more of the allowed characters (alphanumeric, dashes (`-`) and
 *   periods (`.`)).
 * - A `label` cannot begin or end with a dash (`-`) or a period (`.`).
 * - A `label` cannot be longer than 63 characters.
 * - The whole address cannot be longer than 254 characters.
 *
 * ## Implementation background
 *
 * This regexp was ported over from AngularJS (see there for git history):
 * https://github.com/angular/angular.js/blob/c133ef836/src/ng/directive/input.js#L27
 * It is based on the
 * [WHATWG version](https://html.spec.whatwg.org/multipage/input.html#valid-e-mail-address) with
 * some enhancements to incorporate more RFC rules (such as rules related to domain names and the
 * lengths of different parts of the address). The main differences from the WHATWG version are:
 *   - Disallow `local-part` to begin or end with a period (`.`).
 *   - Disallow `local-part` length to exceed 64 characters.
 *   - Disallow total address length to exceed 254 characters.
 *
 * See [this commit](https://github.com/angular/angular.js/commit/f3f5cf72e) for more details.

     * (`RegExp` preserves the index of the last match when the global or sticky flag is used).
     * Due to this behavior, it is recommended that when using
     * `Validators.pattern` you **do not** pass in a `RegExp` object with either the global or sticky
     * flag enabled.
     *
     * ```typescript
     * // Not recommended (since the `g` flag is used)
     * const controlOne = new FormControl('1', Validators.pattern(/foo/g));
     *
     * // Good
     * const controlTwo = new FormControl('1', Validators.pattern(/foo/));
     * ```
     *
     * @param pattern A regular expression to be used as is to test the values, or a string.
     * If a string is passed, the `^` character is prepended and the `$` character is
     * appended to the provided string (if not already present), and the resulting regular
     * expression is used to test the values.
     *
     * @returns A validator function that returns an error map with the

/**
 * Tracks the value and validation status of an individual form control.
 *
 * This is one of the three fundamental building blocks of Angular forms, along with
 * `FormGroup` and `FormArray`. It extends the `AbstractControl` class that
 * implements most of the base functionality for accessing the value, validation status,
 * user interactions and events. See [usage examples below](#usage-notes).
 *
 * @see `AbstractControl`
 * @see [Reactive Forms Guide](guide/reactive-forms)
 * @see [Usage Notes](#usage-notes)
 *
 * @usageNotes
 *
 * ### Initializing Form Controls
 *
 * Instantiate a `FormControl`, with an initial value.
 *
 * ```ts
 * const control = new FormControl('some value');
 * console.log(control.value);     // 'some value'
 *```
 *
 * The following example initializes the control with a form state object. The `value`
 * and `disabled` keys are required in this case.
 *
 * ```ts
 * const control = new FormControl({ value: 'n/a', disabled: true });
 * console.log(control.value);     // 'n/a'
 * console.log(control.status);    // 'DISABLED'
 * ```
 *
 * The following example initializes the control with a synchronous validator.
 *
 * ```ts
 * const control = new FormControl('', Validators.required);
 * console.log(control.value);      // ''
 * console.log(control.status);     // 'INVALID'
 * ```
 *
 * The following example initializes the control using an options object.
 *
 * ```ts
 * const control = new FormControl('', {
 *    validators: Validators.required,
 *    asyncValidators: myAsyncValidator
 * });
 * ```
 *
 * ### Configure the control to update on a blur event
 *
 * Set the `updateOn` option to `'blur'` to update on the blur `event`.
 *
 * ```ts
 * const control = new FormControl('', { updateOn: 'blur' });
 * ```
 *
 * ### Configure the control to update on a submit event
 *
 * Set the `updateOn` option to `'submit'` to update on a submit `event`.
 *
 * ```ts
 * const control = new FormControl('', { updateOn: 'submit' });
 * ```
 *
 * ### Reset the control back to an initial value
 *
 * You reset to a specific form state by passing through a standalone
 * value or a form state object that contains both a value and a disabled state
 * (these are the only two properties that cannot be calculated).
 *
 * ```ts
 * const control = new FormControl('Nancy');
 *
 * console.log(control.value); // 'Nancy'
 *
 * control.reset('Drew');
 *
 * console.log(control.value); // 'Drew'
 * ```
 *
 * ### Reset the control back to an initial value and disabled
 *
 * ```
 * const control = new FormControl('Nancy');
 *
 * console.log(control.value); // 'Nancy'
 * console.log(control.status); // 'VALID'
 *
 * control.reset({ value: 'Drew', disabled: true });
 *
 * console.log(control.value); // 'Drew'
 * console.log(control.status); // 'DISABLED'
 * ```

/**
 * Tracks the value and validity state of a group of `FormControl` instances.
 *
 * A `FormGroup` aggregates the values of each child `FormControl` into one object,
 * with each control name as the key.  It calculates its status by reducing the status values
 * of its children. For example, if one of the controls in a group is invalid, the entire
 * group becomes invalid.
 *
 * `FormGroup` is one of the three fundamental building blocks used to define forms in Angular,
 * along with `FormControl` and `FormArray`.
 *
 * When instantiating a `FormGroup`, pass in a collection of child controls as the first
 * argument. The key for each child registers the name for the control.
 *
 * @usageNotes
 *
 * ### Create a form group with 2 controls
 *
 * ```
 * const form = new FormGroup({
 *   first: new FormControl('Nancy', Validators.minLength(2)),
 *   last: new FormControl('Drew'),
 * });
 *
 * console.log(form.value);   // {first: 'Nancy', last; 'Drew'}
 * console.log(form.status);  // 'VALID'
 * ```
 *
 * ### Create a form group with a group-level validator
 *
 * You include group-level validators as the second arg, or group-level async
 * validators as the third arg. These come in handy when you want to perform validation
 * that considers the value of more than one child control.
 *
 * ```
 * const form = new FormGroup({
 *   password: new FormControl('', Validators.minLength(2)),
 *   passwordConfirm: new FormControl('', Validators.minLength(2)),
 * }, passwordMatchValidator);
 *
 *
 * function passwordMatchValidator(g: FormGroup) {
 *    return g.get('password').value === g.get('passwordConfirm').value
 *       ? null : {'mismatch': true};
 * }
 * ```
 *
 * Like `FormControl` instances, you choose to pass in
 * validators and async validators as part of an options object.
 *
 * ```
 * const form = new FormGroup({
 *   password: new FormControl('')
 *   passwordConfirm: new FormControl('')
 * }, { validators: passwordMatchValidator, asyncValidators: otherValidator });
 * ```
 *
 * ### Set the updateOn property for all controls in a form group
 *
 * The options object is used to set a default value for each child
 * control's `updateOn` property. If you set `updateOn` to `'blur'` at the
 * group level, all child controls default to 'blur', unless the child
 * has explicitly specified a different `updateOn` value.
 *
 * ```ts
 * const c = new FormGroup({
 *   one: new FormControl()
 * }, { updateOn: 'blur' });
 * ```

/**
 * Tracks the value and validity state of an array of `FormControl`,
 * `FormGroup` or `FormArray` instances.
 *
 * A `FormArray` aggregates the values of each child `FormControl` into an array.
 * It calculates its status by reducing the status values of its children. For example, if one of
 * the controls in a `FormArray` is invalid, the entire array becomes invalid.
 *
 * `FormArray` is one of the three fundamental building blocks used to define forms in Angular,
 * along with `FormControl` and `FormGroup`.
 *
 * @usageNotes
 *
 * ### Create an array of form controls
 *
 * ```
 * const arr = new FormArray([
 *   new FormControl('Nancy', Validators.minLength(2)),
 *   new FormControl('Drew'),
 * ]);
 *
 * console.log(arr.value);   // ['Nancy', 'Drew']
 * console.log(arr.status);  // 'VALID'
 * ```
 *
 * ### Create a form array with array-level validators
 *
 * You include array-level validators and async validators. These come in handy
 * when you want to perform validation that considers the value of more than one child
 * control.
 *
 * The two types of validators are passed in separately as the second and third arg
 * respectively, or together as part of an options object.
 *
 * ```
 * const arr = new FormArray([
 *   new FormControl('Nancy'),
 *   new FormControl('Drew')
 * ], {validators: myValidator, asyncValidators: myAsyncValidator});
 * ```
 *
 * ### Set the updateOn property for all controls in a form array
 *
 * The options object is used to set a default value for each child
 * control's `updateOn` property. If you set `updateOn` to `'blur'` at the
 * array level, all child controls default to 'blur', unless the child
 * has explicitly specified a different `updateOn` value.
 *
 * ```ts
 * const arr = new FormArray([
 *    new FormControl()
 * ], {updateOn: 'blur'});
 * ```
 *
 * ### Adding or removing controls from a form array
 *
 * To change the controls in the array, use the `push`, `insert`, `removeAt` or `clear` methods
 * in `FormArray` itself. These methods ensure the controls are properly tracked in the
 * form's hierarchy. Do not modify the array of `AbstractControl`s used to instantiate
 * the `FormArray` directly, as that result in strange and unexpected behavior such
 * as broken change detection.

 * @description
 * Creates a top-level `FormGroup` instance and binds it to a form
 * to track aggregate form value and validation status.
 *
 * As soon as you import the `FormsModule`, this directive becomes active by default on
 * all `<form>` tags.  You don't need to add a special selector.
 *
 * You optionally export the directive into a local template variable using `ngForm` as the key
 * (ex: `#myForm="ngForm"`). This is optional, but useful.  Many properties from the underlying
 * `FormGroup` instance are duplicated on the directive itself, so a reference to it
 * gives you access to the aggregate value and validity status of the form, as well as
 * user interaction properties like `dirty` and `touched`.
 *
 * To register child controls with the form, use `NgModel` with a `name`
 * attribute. You may use `NgModelGroup` to create sub-groups within the form.
 *
 * If necessary, listen to the directive's `ngSubmit` event to be notified when the user has
 * triggered a form submission. The `ngSubmit` event emits the original form
 * submission event.
 *
 * In template driven forms, all `<form>` tags are automatically tagged as `NgForm`.
 * To import the `FormsModule` but skip its usage in some forms,
 * for example, to use native HTML5 validation, add the `ngNoForm` and the `<form>`
 * tags won't create an `NgForm` directive. In reactive forms, using `ngNoForm` is
 * unnecessary because the `<form>` tags are inert. In that case, you would
 * refrain from using the `formGroup` directive.
 *
 * @usageNotes
 *
 * ### Listening for form submission
 *
 * The following example shows how to capture the form values from the "ngSubmit" event.
 *
 * {@example forms/ts/simpleForm/simple_form_example.ts region='Component'}
 *
 * ### Setting the update options
 *
 * The following example shows you how to change the "updateOn" option from its default using
 * ngFormOptions.
 *
 * ```html
 * <form [ngFormOptions]="{updateOn: 'blur'}">
 *    <input name="one" ngModel>  <!-- this ngModel will update on blur -->
 * </form>
 * ```
 *
 * ### Native DOM validation UI
 *
 * In order to prevent the native DOM form validation UI from interfering with Angular's form
 * validation, Angular automatically adds the `novalidate` attribute on any `<form>` whenever
 * `FormModule` or `ReactiveFormModule` are imported into the application.
 * If you want to explicitly enable native DOM validation UI with Angular forms, you can add the
 * `ngNativeValidate` attribute to the `<form>` element:
 *
 * ```html
 * <form ngNativeValidate>
 *   ...
 * </form>
 * ```

/**
 * @description
 * Creates a `FormControl` instance from a domain model and binds it
 * to a form control element.
 *
 * The `FormControl` instance tracks the value, user interaction, and
 * validation status of the control and keeps the view synced with the model. If used
 * within a parent form, the directive also registers itself with the form as a child
 * control.
 *
 * This directive is used by itself or as part of a larger form. Use the
 * `ngModel` selector to activate it.
 *
 * It accepts a domain model as an optional `Input`. If you have a one-way binding
 * to `ngModel` with `[]` syntax, changing the domain model's value in the component
 * class sets the value in the view. If you have a two-way binding with `[()]` syntax
 * (also known as 'banana-in-a-box syntax'), the value in the UI always syncs back to
 * the domain model in your class.
 *
 * To inspect the properties of the associated `FormControl` (like the validity state),
 * export the directive into a local template variable using `ngModel` as the key (ex:
 * `#myVar="ngModel"`). You can then access the control using the directive's `control` property.
 * However, the most commonly used properties (like `valid` and `dirty`) also exist on the control
 * for direct access. See a full list of properties directly available in
 * `AbstractControlDirective`.
 *
 * @see `RadioControlValueAccessor`
 * @see `SelectControlValueAccessor`
 *
 * @usageNotes
 *
 * ### Using ngModel on a standalone control
 *
 * The following examples show a simple standalone control using `ngModel`:
 *
 * {@example forms/ts/simpleNgModel/simple_ng_model_example.ts region='Component'}
 *
 * When using the `ngModel` within `<form>` tags, you'll also need to supply a `name` attribute
 * so that the control can be registered with the parent form under that name.
 *
 * In the context of a parent form, it's often unnecessary to include one-way or two-way binding,
 * as the parent form syncs the value for you. You access its properties by exporting it into a
 * local template variable using `ngForm` such as (`#f="ngForm"`). Use the variable where
 * needed on form submission.
 *
 * If you do need to populate initial values into your form, using a one-way binding for
 * `ngModel` tends to be sufficient as long as you use the exported form's value rather
 * than the domain model's value on submit.
 *
 * ### Using ngModel within a form
 *
 * The following example shows controls using `ngModel` within a form:
 *
 * {@example forms/ts/simpleForm/simple_form_example.ts region='Component'}
 *
 * ### Using a standalone ngModel within a group
 *
 * The following example shows you how to use a standalone ngModel control
 * within a form. This controls the display of the form, but doesn't contain form data.
 *
 * ```html
 * <form>
 *   <input name="login" ngModel placeholder="Login">
 *   <input type="checkbox" ngModel [ngModelOptions]="{standalone: true}"> Show more options?
 * </form>
 * <!-- form value: {login: ''} -->
 * ```
 *
 * ### Setting the ngModel `name` attribute through options
 *
 * The following example shows you an alternate way to set the name attribute. Here,
 * an attribute identified as name is used within a custom form control component. To still be able
 * to specify the NgModel's name, you must specify it using the `ngModelOptions` input instead.
 *
 * ```html
 * <form>
 *   <my-custom-form-control name="Nancy" ngModel [ngModelOptions]="{name: 'user'}">
 *   </my-custom-form-control>
 * </form>
 * <!-- form value: {user: ''} -->
 * ```

 * Syncs a nested `FormGroup` to a DOM element.
 *
 * This directive can only be used with a parent `FormGroupDirective`.
 *
 * It accepts the string name of the nested `FormGroup` to link, and
 * looks for a `FormGroup` registered with that name in the parent
 * `FormGroup` instance you passed into `FormGroupDirective`.
 *
 * Use nested form groups to validate a sub-group of a
 * form separately from the rest or to group the values of certain

 * ### Access the group by name
 *
 * The following example uses the {@link AbstractControl#get get} method to access the
 * associated `FormGroup`
 *
 * ```ts
 *   this.form.get('name');
 * ```
 *
 * ### Access individual controls in the group
 *
 * The following example uses the {@link AbstractControl#get get} method to access
 * individual controls within the group using dot syntax.
 *
 * ```ts
 *   this.form.get('name.first');
 * ```
 *
 * ### Register a nested `FormGroup`.
 *
 * The following example registers a nested *name* `FormGroup` within an existing `FormGroup`,

/**
 * @description
 * The `ControlValueAccessor` for writing select control values and listening to select control
 * changes. The value accessor is used by the `FormControlDirective`, `FormControlName`, and
 * `NgModel` directives.
 *
 * @usageNotes
 *
 * ### Using select controls in a reactive form
 *
 * The following examples show how to use a select control in a reactive form.
 *
 * {@example forms/ts/reactiveSelectControl/reactive_select_control_example.ts region='Component'}
 *
 * ### Using select controls in a template-driven form
 *
 * To use a select in a template-driven form, simply add an `ngModel` and a `name`
 * attribute to the main `<select>` tag.
 *
 * {@example forms/ts/selectControl/select_control_example.ts region='Component'}
 *
 * ### Customizing option selection
 *
 * Angular uses object identity to select option. It's possible for the identities of items
 * to change while the data does not. This can happen, for example, if the items are produced
 * from an RPC to the server, and that RPC is re-run. Even if the data hasn't changed, the
 * second response will produce objects with different identities.
 *
 * To customize the default option comparison algorithm, `<select>` supports `compareWith` input.
 * `compareWith` takes a **function** which has two arguments: `option1` and `option2`.
 * If `compareWith` is given, Angular selects option by the return value of the function.
 *
 * ```ts
 * const selectedCountriesControl = new FormControl();
 * ```
 *
 * ```
 * <select [compareWith]="compareFn"  [formControl]="selectedCountriesControl">
 *     <option *ngFor="let country of countries" [ngValue]="country">
 *         {{country.name}}
 *     </option>
 * </select>
 *
 * compareFn(c1: Country, c2: Country): boolean {
 *     return c1 && c2 ? c1.id === c2.id : c1 === c2;
 * }
 * ```
 *
 * **Note:** We listen to the 'change' event because 'input' events aren't fired
 * for selects in IE, see:
 * https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/input_event#browser_compatibility
 *
 * @ngModule ReactiveFormsModule
 * @ngModule FormsModule

/**
 * DomSanitizer helps preventing Cross Site Scripting Security bugs (XSS) by sanitizing
 * values to be safe to use in the different DOM contexts.
 *
 * For example, when binding a URL in an `<a [href]="someValue">` hyperlink, `someValue` will be
 * sanitized so that an attacker cannot inject e.g. a `javascript:` URL that would execute code on
 * the website.
 *
 * In specific situations, it might be necessary to disable sanitization, for example if the
 * application genuinely needs to produce a `javascript:` style link with a dynamic value in it.
 * Users can bypass security by constructing a value with one of the `bypassSecurityTrust...`
 * methods, and then binding to that value from the template.
 *
 * These situations should be very rare, and extraordinary care must be taken to avoid creating a
 * Cross Site Scripting (XSS) security bug!
 *
 * When using `bypassSecurityTrust...`, make sure to call the method as early as possible and as
 * close as possible to the source of the value, to make it easy to verify no security bug is
 * created by its use.
 *
 * It is not required (and not recommended) to bypass security if the value is safe, e.g. a URL that
 * does not start with a suspicious protocol, or an HTML snippet that does not contain dangerous
 * code. The sanitizer leaves safe values intact.
 *
 * @security Calling any of the `bypassSecurityTrust...` APIs disables Angular's built-in
 * sanitization for the value passed in. Carefully check and audit all values and code paths going
 * into this call. Make sure any user data is appropriately escaped for this security context.
 * For more detail, see the [Security Guide](https://g.co/ng/security).

/**
 * @description
 *
 * When applied to an element in a template, makes that element a link
 * that initiates navigation to a route. Navigation opens one or more routed components
 * in one or more `<router-outlet>` locations on the page.
 *
 * Given a route configuration `[{ path: 'user/:name', component: UserCmp }]`,
 * the following creates a static link to the route:
 * `<a routerLink="/user/bob">link to user component</a>`
 *
 * You can use dynamic values to generate the link.
 * For a dynamic link, pass an array of path segments,
 * followed by the params for each segment.
 * For example, `['/team', teamId, 'user', userName, {details: true}]`
 * generates a link to `/team/11/user/bob;details=true`.
 *
 * Multiple static segments can be merged into one term and combined with dynamic segements.
 * For example, `['/team/11/user', userName, {details: true}]`
 *
 * The input that you provide to the link is treated as a delta to the current URL.
 * For instance, suppose the current URL is `/user/(box//aux:team)`.
 * The link `<a [routerLink]="['/user/jim']">Jim</a>` creates the URL
 * `/user/(jim//aux:team)`.
 * See {@link Router#createUrlTree createUrlTree} for more information.
 *
 * @usageNotes
 *
 * You can use absolute or relative paths in a link, set query parameters,
 * control how parameters are handled, and keep a history of navigation states.
 *
 * ### Relative link paths
 *
 * The first segment name can be prepended with `/`, `./`, or `../`.
 * * If the first segment begins with `/`, the router looks up the route from the root of the
 *   app.
 * * If the first segment begins with `./`, or doesn't begin with a slash, the router
 *   looks in the children of the current activated route.
 * * If the first segment begins with `../`, the router goes up one level in the route tree.
 *
 * ### Setting and handling query params and fragments
 *
 * The following link adds a query parameter and a fragment to the generated URL:
 *
 * ```
 * <a [routerLink]="['/user/bob']" [queryParams]="{debug: true}" fragment="education">
 *   link to user component
 * </a>
 * ```
 * By default, the directive constructs the new URL using the given query parameters.
 * The example generates the link: `/user/bob?debug=true#education`.
 *
 * You can instruct the directive to handle query parameters differently
 * by specifying the `queryParamsHandling` option in the link.
 * Allowed values are:
 *
 *  - `'merge'`: Merge the given `queryParams` into the current query params.
 *  - `'preserve'`: Preserve the current query params.
 *
 * For example:
 *
 * ```
 * <a [routerLink]="['/user/bob']" [queryParams]="{debug: true}" queryParamsHandling="merge">
 *   link to user component
 * </a>
 * ```
 *
 * See {@link UrlCreationOptions.queryParamsHandling UrlCreationOptions#queryParamsHandling}.
 *
 * ### Preserving navigation history
 *
 * You can provide a `state` value to be persisted to the browser's
 * [`History.state` property](https://developer.mozilla.org/en-US/docs/Web/API/History#Properties).
 * For example:
 *
 * ```
 * <a [routerLink]="['/user/bob']" [state]="{tracingId: 123}">
 *   link to user component
 * </a>
 * ```
 *
 * Use {@link Router.getCurrentNavigation() Router#getCurrentNavigation} to retrieve a saved
 * navigation-state value. For example, to capture the `tracingId` during the `NavigationStart`
 * event:
 *
 * ```
 * // Get NavigationStart events
 * router.events.pipe(filter(e => e instanceof NavigationStart)).subscribe(e => {
 *   const navigation = router.getCurrentNavigation();
 *   tracingService.trace({id: navigation.extras.state.tracingId});
 * });
 * ```

 * @description
 *
 * Tracks whether the linked route of an element is currently active, and allows you
 * to specify one or more CSS classes to add to the element when the linked route
 * is active.
 *
 * Use this directive to create a visual distinction for elements associated with an active route.
 * For example, the following code highlights the word "Bob" when the router
 * activates the associated route:
 *
 * ```
 * <a routerLink="/user/bob" routerLinkActive="active-link">Bob</a>
 * ```
 *
 * Whenever the URL is either '/user' or '/user/bob', the "active-link" class is
 * added to the anchor tag. If the URL changes, the class is removed.
 *
 * You can set more than one class using a space-separated string or an array.
 * For example:
 *
 * ```
 * <a routerLink="/user/bob" routerLinkActive="class1 class2">Bob</a>
 * <a routerLink="/user/bob" [routerLinkActive]="['class1', 'class2']">Bob</a>
 * ```
 *
 * To add the classes only when the URL matches the link exactly, add the option `exact: true`:
 *
 * ```
 * <a routerLink="/user/bob" routerLinkActive="active-link" [routerLinkActiveOptions]="{exact:
 * true}">Bob</a>
 * ```
 *
 * To directly check the `isActive` status of the link, assign the `RouterLinkActive`
 * instance to a template variable.
 * For example, the following checks the status without assigning any CSS classes:
 *
 * ```
 * <a routerLink="/user/bob" routerLinkActive #rla="routerLinkActive">
 *   Bob {{ rla.isActive ? '(already open)' : ''}}
 * </a>
 * ```
 *
 * You can apply the `RouterLinkActive` directive to an ancestor of linked elements.
 * For example, the following sets the active-link class on the `<div>`  parent tag
 * when the URL is either '/user/jim' or '/user/bob'.
 *
 * ```
 * <div routerLinkActive="active-link" [routerLinkActiveOptions]="{exact: true}">
 *   <a routerLink="/user/jim">Jim</a>
 *   <a routerLink="/user/bob">Bob</a>
 * </div>

 *
 * Acts as a placeholder that Angular dynamically fills based on the current router state.
 *
 * Each outlet can have a unique name, determined by the optional `name` attribute.
 * The name cannot be set or changed dynamically. If not set, default value is "primary".
 *
 * ```
 * <router-outlet></router-outlet>
 * <router-outlet name='left'></router-outlet>
 * <router-outlet name='right'></router-outlet>
 * ```
 *
 * Named outlets can be the targets of secondary routes.
 * The `Route` object for a secondary route has an `outlet` property to identify the target outlet:
 *
 * `{path: <base-path>, component: <component>, outlet: <target_outlet_name>}`
 *
 * Using named outlets and secondary routes, you can target multiple outlets in
 * the same `RouterLink` directive.
 *
 * The router keeps track of separate branches in a navigation tree for each named outlet and
 * generates a representation of that tree in the URL.
 * The URL for a secondary route uses the following syntax to specify both the primary and secondary
 * routes at the same time:
 *
 * `http://base-path/primary-route-path(outlet-name:route-path)`
 *
 * A router outlet emits an activate event when a new component is instantiated,
 * and a deactivate event when a component is destroyed.
 *
 * ```
 * <router-outlet
 *   (activate)='onActivate($event)'
 *   (deactivate)='onDeactivate($event)'></router-outlet>
 * ```

/**
 * Subscribe and listen to
 * [Web Push
 * Notifications](https://developer.mozilla.org/en-US/docs/Web/API/Push_API/Best_Practices) through
 * Angular Service Worker.
 *
 * @usageNotes
 *
 * You can inject a `SwPush` instance into any component or service
 * as a dependency.
 *
 * <code-example path="service-worker/push/module.ts" region="inject-sw-push"
 * header="app.component.ts"></code-example>
 *
 * To subscribe, call `SwPush.requestSubscription()`, which asks the user for permission.
 * The call returns a `Promise` with a new
 * [`PushSubscription`](https://developer.mozilla.org/en-US/docs/Web/API/PushSubscription)
 * instance.
 *
 * <code-example path="service-worker/push/module.ts" region="subscribe-to-push"
 * header="app.component.ts"></code-example>
 *
 * A request is rejected if the user denies permission, or if the browser
 * blocks or does not support the Push API or ServiceWorkers.
 * Check `SwPush.isEnabled` to confirm status.
 *
 * Invoke Push Notifications by pushing a message with the following payload.
 *
 * ```ts
 * {
 *   "notification": {
 *     "actions": NotificationAction[],
 *     "badge": USVString,
 *     "body": DOMString,
 *     "data": any,
 *     "dir": "auto"|"ltr"|"rtl",
 *     "icon": USVString,
 *     "image": USVString,
 *     "lang": DOMString,
 *     "renotify": boolean,
 *     "requireInteraction": boolean,
 *     "silent": boolean,
 *     "tag": DOMString,
 *     "timestamp": DOMTimeStamp,
 *     "title": DOMString,
 *     "vibrate": number[]
 *   }
 * }
 * ```
 *
 * Only `title` is required. See `Notification`
 * [instance
 * properties](https://developer.mozilla.org/en-US/docs/Web/API/Notification#Instance_properties).
 *
 * While the subscription is active, Service Worker listens for
 * [PushEvent](https://developer.mozilla.org/en-US/docs/Web/API/PushEvent)
 * occurrences and creates
 * [Notification](https://developer.mozilla.org/en-US/docs/Web/API/Notification)
 * instances in response.
 *
 * Unsubscribe using `SwPush.unsubscribe()`.
 *
 * An application can subscribe to `SwPush.notificationClicks` observable to be notified when a user
 * clicks on a notification. For example:
 *
 * <code-example path="service-worker/push/module.ts" region="subscribe-to-notification-clicks"
 * header="app.component.ts"></code-example>
 *
 * You can read more on handling notification clicks in the [Service worker notifications
 * guide](guide/service-worker-notifications).
