/**
* 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
*
*
...
* ```
*
* ### 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: `
*
*
*
* `,
* 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.
*
* @publicApi
*/
function trigger(name, definitions) {
return { type: 7 /* Trigger */, name, definitions, options: {} };
}
/**
* 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" })
* ])
* ```

* ### Usage
*
* In the following example, the offset values describe

/**
* Declares an animation transition as a sequence of animation steps to run when a given

* 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
*
*
...
* ```
*
* 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
*
...
* // in the component metadata
* trigger('openClose', [
* state('true', style({ height: '*' })),
* state('false', style({ height: '0px' })),
* transition('false <=> true', animate(500))
* ])
* ```

* - `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: `
*
*
Title
*
* Blah blah blah
*
*
* `,
* 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';
* }
* }
* ```
*
* @publicApi
*/

return { type: 11 /* Query */, selector, animation, options };
}
/**
* 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
*
*
*
*
*
* {{ item }}
*
*
* ```
*
* 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 }))
* ])
* ]),
* query(':enter', [
* 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.

*
* ```
* 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
* - `/my/app/user/123/` **is not** normalized
*

*
* * `ngComponentOutletContent`: Optional list of projectable nodes to insert into the content

/**
* A [structural directive](guide/structural-directives) that renders
* a template for each item in a collection.
* The directive is placed on an element, which becomes the parent
* of the cloned templates.
*
* The `ngForOf` directive is generally used in the
* [shorthand form](guide/structural-directives#asterisk) `*ngFor`.
* 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 `
` element.
*
* ```
*
...
* ```
*
* The shorthand form expands into a long form that uses the `ngForOf` selector
* on an `` element.
* The content of the `` element is the `
` element that held the
* short-form directive.
*
* Here is the expanded version of the short-form example.
*
* ```
*
*
...
*
* ```
*
* 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:
*
* ```
*
* {{i}}/{{users.length}}. {{user}} default
*
* ```
*
* The following exported values can be aliased to local variables:
*
* - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).
* - `ngForOf: NgIterable`: 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 `` 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.
*
* @see [Structural Directives](guide/structural-directives)

/**
* 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 `` element.
*
* Simple form with shorthand syntax:
*
* ```
*
Content to render when condition is true.
* ```
*
* Simple form with expanded syntax:
*
* ```
*
Content to render when condition is
* true.
* ```
*
* Form with an "else" block:
*
* ```
*
Content to render when condition is true.
* Content to render when condition is false.
* ```
*
* Shorthand form with "then" and "else" blocks:
*
* ```
*
* Content to render when condition is true.
* Content to render when condition is false.
* ```
*
* Form with storing the value locally:
*
* ```
*
{{value}}
* Content to render when value is null.
* ```
*
* @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 `` 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 `` 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.
*
* ```
*
* ...
*
*
*
*
Loading...
*
* ```
*
* You can see that the "else" clause references the ``
* 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 `` tag, with `ngIf` and `ngIfElse` directives.
* The anchor element containing the template for the "then" clause becomes
* the content of this unlabeled `` tag.
*
* ```
*
*
* ...
*
*
*
*
*
Loading...
*
* ```
*
* 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).

* 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.

/**
* @ngModule CommonModule
* @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
*
* | Option | Equivalent to | Examples (given in `en-US` locale) |
* |---------------|-------------------------------------|-------------------------------------------------|
* | `'short'` | `'M/d/yy, h:mm a'` | `6/15/15, 9:03 AM` |
* | `'medium'` | `'MMM d, y, h:mm:ss a'` | `Jun 15, 2015, 9:03:01 AM` |
* | `'long'` | `'MMMM d, y, h:mm:ss a z'` | `June 15, 2015 at 9:03:01 AM GMT+1` |
* | `'full'` | `'EEEE, MMMM d, y, h:mm:ss a zzzz'` | `Monday, June 15, 2015 at 9:03:01 AM GMT+01:00` |
* | `'shortDate'` | `'M/d/yy'` | `6/15/15` |
* | `'mediumDate'`| `'MMM d, y'` | `Jun 15, 2015` |
* | `'longDate'` | `'MMMM d, y'` | `June 15, 2015` |
* | `'fullDate'` | `'EEEE, MMMM d, y'` | `Monday, June 15, 2015` |
* | `'shortTime'` | `'h:mm a'` | `9:03 AM` |
* | `'mediumTime'`| `'h:mm:ss a'` | `9:03:01 AM` |
* | `'longTime'` | `'h:mm:ss a z'` | `9:03:01 AM GMT+1` |
* | `'fullTime'` | `'h:mm:ss a zzzz'` | `9:03:01 AM GMT+01:00` |
*
* ### Custom format options
*
* You can construct a format string using symbols to specify the components
* of a date-time value, as described in the following table.
* Format details depend on the locale.
* Fields marked with (*) are only available in the extra data set for the given locale.
*
* | Field type | Format | Description | Example Value |
* |-------------------- |-------------|---------------------------------------------------------------|------------------------------------------------------------|
* | Era | G, GG & GGG | Abbreviated | AD |
* | | GGGG | Wide | Anno Domini |
* | | GGGGG | Narrow | A |
* | Year | y | Numeric: minimum digits | 2, 20, 201, 2017, 20173 |
* | | yy | Numeric: 2 digits + zero padded | 02, 20, 01, 17, 73 |

* ### 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: `
*
Today is {{today | date}}
*
Or if you prefer, {{today | date:'fullDate'}}
*
The time is {{today | date:'h:mm a z'}}
*
`
* })
* // Get the current date and time as a date-time value.
* export class DatePipeComponent {
* today: number = Date.now();
* }
* ```

* @ngModule CommonModule
* @description
*
* Creates a new `Array` or `String` containing a subset (slice) of the elements.
*
* @usageNotes
*
* All behavior is based on the expected behavior of the JavaScript API `Array.prototype.slice()`
* and `String.prototype.slice()`.
*
* When operating on an `Array`, the returned `Array` is always a copy even when all
* the elements are being returned.
*
* When operating on a blank value, the pipe returns the blank value.
*
* ### List Example
*
* This `ngFor` example:
*
* {@example common/pipes/ts/slice_pipe.ts region='SlicePipe_list'}
*
* produces the following:
*
* ```html
*
b
*
c
* ```
*
* ### String Examples
*
* {@example common/pipes/ts/slice_pipe.ts region='SlicePipe_string'}

*
* You can pass an `HttpRequest` directly as the only parameter. In this case,

*
* Alternatively you can pass an HTTP method as the first parameter,
* a URL string as the second, and an options hash containing the request body as the third.
* See `addBody()`. In this case, the specified `responseType` and `observe` options determine the
* type of returned observable.
* * The `responseType` value determines how a successful response body is parsed.
* * If `responseType` is the default `json`, you can pass a type interface for the resulting
* object as a type parameter to the call.
*
* The `observe` value determines the return type, according to what you are interested in
* observing.
* * An `observe` value of events returns an observable of the raw `HttpEvent` stream, including
* progress events by default.
* * An `observe` value of response returns an observable of `HttpResponse`,
* where the `T` parameter depends on the `responseType` and any optionally provided type
* parameter.
* * An `observe` value of body returns an observable of `` with the same `T` body type.
