/**
 * 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 additional level of type safety.
 *
 * ```
 * interface MyInterface {...}
 * var 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. See below for an example.
 *
 * Additionally, if a `factory` is specified you can also specify the `providedIn` option, which
 * overrides the above behavior and marks the token as belonging to a particular `@NgModule`. As
 * mentioned above, `'root'` is the default value for `providedIn`.
 *
 * @usageNotes
 * ### Basic Example
 *
 * ### Plain InjectionToken

/**
 * A pattern that recognizes a commonly useful subset of URLs that are safe.
 *
 * This regular expression matches a subset of URLs that will not cause script
 * execution if used in URL context within a HTML document. Specifically, this
 * 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
 *     allows that by allowing colons only after one of the characters [/?#].
 *     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
 * that. More importantly, it disallows masking of a colon,
 * e.g. "javascript&#58;...".
 *
 * This regular expression was taken from the Closure sanitization library.

 * Returns the matching `LContext` data for a given DOM node, directive or component instance.
 *
 * This function will examine the provided DOM element, component, or directive instance\'s
 * 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).

/**
 * Base class for Angular Views, provides change detection functionality.
 * A change-detection tree collects all views that are to be checked for changes.
 * Use the methods to add and remove views from the tree, initiate change-detection,
 * and explicitly mark views as _dirty_, meaning that they have changed and need to be rerendered.
 *
 * @usageNotes
 *
 * 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](http://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.
 *
 * <code-example path="core/ts/change_detect/change-detection.ts" region="reattach"></code-example>

/**
 * 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 {

 * }
 *
 * 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.

 * })
 * class MyComponent{

 * 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 "

 *     ɵɵstyleMap({color: '#005'});

 *
 * @Directive({

 * })
 * class Style2Directive {

 *   @HostBinding('style.color') color = '#008';
 *
 *   static ngDir = ... {

 * })
 * 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
 * |---|------------|-----------------|--------------
 * |...|            |                 |

 * |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.

 * ```

 * when `[style.color]="tmplExp"` executes it creates this data structure.
 * ```
 *  ['', 'color', 'color', 'red', 'width', '100px'],

 *
 * The reason for this is that the template instruction does not know if there are styling
 * instructions and must assume that there are none and must collect all of the static styling.
 * (both
 * `color' and 'width`)
 *
 * When `'[style.color]': 'dirExp',` executes we need to insert a new data into the linked list.

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

 * Notice that the template statics is now wrong as it incorrectly contains `width` so we need to

 * Search for styling value with higher priority which is overwriting current value, or a
 * value of lower priority to which we should fall back if the value is `undefined`.
 *
 * When value is being applied at a location, related values need to be consulted.
 * - If there is a higher priority binding, we should be using that one instead.
 *   For example `<div  [style]="{color:exp1}" [style.color]="exp2">` change to `exp1`
 *   requires that we check `exp2` to see if it is set to value other than `undefined`.
 * - If there is a lower priority binding and we are changing to `undefined`
 *   For example `<div  [style]="{color:exp1}" [style.color]="exp2">` change to `exp2` to
 *   `undefined` requires that we check `exp1` (and static values) and use that as new value.
 *
 * NOTE: The styling stores two values.
 * 1. The raw value which came from the application is stored at `index + 0` location. (This value
 *    is used for dirty checking).
 * 2. The normalized value (converted to `KeyValueArray` if map and sanitized) is stored at `index +
 * 1`.
 *    The advantage of storing the sanitized value is that once the value is written we don't need
 *    to worry about sanitizing it later or keeping track of the sanitizer.
 *
 * @param tData `TData` used for traversing the priority.
 * @param tNode `TNode` to use for resolving static styling. Also controls search direction.
 *   - `TNode` search next and quit as soon as `isStylingValuePresent(value)` is true.
 *      If no value found consult `tNode.residualStyle`/`tNode.residualClass` for default value.
 *   - `null` search prev and go all the way to end. Return last value where
 *     `isStylingValuePresent(value)` is true.
 * @param lView `LView` used for retrieving the actual values.
 * @param prop Property which we are interested in.

// 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().

     * 3. However in real templates the order might be different: i.e. �#1:1� and/or �#3:2� may go in
     * front of �#6�. The post processing step restores the right order by keeping track of the
     * template id stack and looks for placeholders that belong to the currently active template.

 *   and end of DOM element that were embedded in the original translation block. The placeholder
 *   `index` points to the element index in the template instructions set. An optional `block` that
 *   matches the sub-template in which it was declared.
 * - `�*{index}:{block}�`/`�/*{index}:{block}�`: *Sub-template Placeholder*: Sub-templates must be
 *   split up and translated separately in each angular template function. The `index` points to the

/**
 * An injectable service for executing work inside or outside of the Angular zone.
 *
 * The most common use of this service is to optimize performance when starting a work consisting of
 * one or more asynchronous tasks that don't require UI updates or error handling to be handled by
 * Angular. Such tasks can be kicked off via {@link #runOutsideAngular} and if needed, these tasks
 * can reenter the Angular zone via {@link #run}.
 *
 * <!-- TODO: add/fix links to:
 *   - docs explaining zones and the use of zones in Angular and change-detection
 *   - link to runOutsideAngular/run (throughout this file!)

/**
 * 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));
 * }
 * ```
 *
