* Each Angular component requires a single `@Component` annotation. The `@Component`
* annotation specifies when a component is instantiated, and which properties and hostListeners it
* binds to.
*
* When a component is instantiated, Angular
* - creates a shadow DOM for the component.
* - loads the selected template into the shadow DOM.
* - creates all the injectable objects configured with `providers` and `viewProviders`.
*
* All template expressions and statements are then evaluated against the component instance.
*
* ## Lifecycle hooks
*

/**
* Directives allow you to attach behavior to elements in the DOM.
*
* {@link DirectiveMetadata}s with an embedded view are called {@link ComponentMetadata}s.
*
* A directive consists of a single directive annotation and a controller class. When the
* directive's `selector` matches
* elements in the DOM, the following steps occur:
*
* 1. For each directive, the `ElementInjector` attempts to resolve the directive's constructor
* arguments.
* 2. Angular instantiates directives for each matched element using `ElementInjector` in a
* depth-first order,
* as declared in the HTML.
*
* ## Understanding How Injection Works
*
* There are three stages of injection resolution.
* - *Pre-existing Injectors*:
* - The terminal {@link Injector} cannot resolve dependencies. It either throws an error or, if
* the dependency was
* specified as `@Optional`, returns `null`.
* - The platform injector resolves browser singleton resources, such as: cookies, title,
* location, and others.
* - *Component Injectors*: Each component instance has its own {@link Injector}, and they follow
* the same parent-child hierarchy
* as the component instances in the DOM.
* - *Element Injectors*: Each component instance has a Shadow DOM. Within the Shadow DOM each
* element has an `ElementInjector`
* which follow the same parent-child hierarchy as the DOM elements themselves.
*
* When a template is instantiated, it also must instantiate the corresponding directives in a
* depth-first order. The
* current `ElementInjector` resolves the constructor dependencies for each directive.
*
* Angular then resolves dependencies as follows, according to the order in which they appear in the
* {@link ViewMetadata}:
*
* 1. Dependencies on the current element
* 2. Dependencies on element injectors and their parents until it encounters a Shadow DOM boundary
* 3. Dependencies on component injectors and their parents until it encounters the root component
* 4. Dependencies on pre-existing injectors
*
*
* The `ElementInjector` can inject other directives, element-specific special objects, or it can
* delegate to the parent
* injector.
*
* To inject other directives, declare the constructor parameter as:
* - `directive:DirectiveType`: a directive on the current element only
* - `@Host() directive:DirectiveType`: any directive that matches the type between the current
* element and the
* Shadow DOM root.
* - `@Query(DirectiveType) query:QueryList<DirectiveType>`: A live collection of direct child
* directives.
* - `@QueryDescendants(DirectiveType) query:QueryList<DirectiveType>`: A live collection of any
* child directives.
*
* To inject element-specific special objects, declare the constructor parameter as:
* - `element: ElementRef` to obtain a reference to logical element in the view.
* - `viewContainer: ViewContainerRef` to control child template instantiation, for
* {@link DirectiveMetadata} directives only
* - `bindingPropagation: BindingPropagation` to control change detection in a more granular way.
*
* ### Example
*
* The following example demonstrates how dependency injection resolves constructor arguments in
* practice.
*
*
* Assume this HTML template:
*
* ```
* <div dependency="1">
* <div dependency="2">
* <div dependency="3" my-directive>
* <div dependency="4">
* <div dependency="5"></div>
* </div>
* <div dependency="6"></div>
* </div>
* </div>
* </div>
* ```
*
* With the following `dependency` decorator and `SomeService` injectable class.
*
* ```
* @Injectable()
* class SomeService {
* }
*
* @Directive({
* selector: '[dependency]',
* inputs: [
* 'id: dependency'
* ]
* })
* class Dependency {
* id:string;
* }
* ```
*
* Let's step through the different ways in which `MyDirective` could be declared...
*
*
* ### No injection
*
* Here the constructor is declared with no arguments, therefore nothing is injected into
* `MyDirective`.
*
* ```
* @Directive({ selector: '[my-directive]' })
* class MyDirective {
* constructor() {
* }
* }
* ```
*
* This directive would be instantiated with no dependencies.
*
*
* ### Component-level injection
*
* Directives can inject any injectable instance from the closest component injector or any of its
* parents.
*
* Here, the constructor declares a parameter, `someService`, and injects the `SomeService` type
* from the parent
* component's injector.
* ```
* @Directive({ selector: '[my-directive]' })
* class MyDirective {
* constructor(someService: SomeService) {
* }
* }
* ```
*
* This directive would be instantiated with a dependency on `SomeService`.
*
*
* ### Injecting a directive from the current element
*
* Directives can inject other directives declared on the current element.
*
* ```
* @Directive({ selector: '[my-directive]' })
* class MyDirective {
* constructor(dependency: Dependency) {
* expect(dependency.id).toEqual(3);
* }
* }
* ```
* This directive would be instantiated with `Dependency` declared at the same element, in this case
* `dependency="3"`.
*
* ### Injecting a directive from any ancestor elements
*
* Directives can inject other directives declared on any ancestor element (in the current Shadow
* DOM), i.e. on the current element, the
* parent element, or its parents.
* ```
* @Directive({ selector: '[my-directive]' })
* class MyDirective {
* constructor(@Host() dependency: Dependency) {
* expect(dependency.id).toEqual(2);
* }
* }
* ```
*
* `@Host` checks the current element, the parent, as well as its parents recursively. If
* `dependency="2"` didn't
* exist on the direct parent, this injection would
* have returned
* `dependency="1"`.
*
*
* ### Injecting a live collection of direct child directives
*
*
* A directive can also query for other child directives. Since parent directives are instantiated
* before child directives, a directive can't simply inject the list of child directives. Instead,
* the directive injects a {@link QueryList}, which updates its contents as children are added,
* removed, or moved by a directive that uses a {@link ViewContainerRef} such as a `ngFor`, an
* `ngIf`, or an `ngSwitch`.
*
* ```
* @Directive({ selector: '[my-directive]' })
* class MyDirective {
* constructor(@Query(Dependency) dependencies:QueryList<Dependency>) {
* }
* }
* ```
*
* This directive would be instantiated with a {@link QueryList} which contains `Dependency` 4 and
* 6. Here, `Dependency` 5 would not be included, because it is not a direct child.
*
* ### Injecting a live collection of descendant directives
*
* By passing the descendant flag to `@Query` above, we can include the children of the child
* elements.
*
* ```
* @Directive({ selector: '[my-directive]' })
* class MyDirective {
* constructor(@Query(Dependency, {descendants: true}) dependencies:QueryList<Dependency>) {
* }
* }
* ```
*
* This directive would be instantiated with a Query which would contain `Dependency` 4, 5 and 6.
*
* ### Optional injection
*
* The normal behavior of directives is to return an error when a specified dependency cannot be
* resolved. If you
* would like to inject `null` on unresolved dependency instead, you can annotate that dependency
* with `@Optional()`.
* This explicitly permits the author of a template to treat some of the surrounding directives as
* optional.
*
* ```
* @Directive({ selector: '[my-directive]' })
* class MyDirective {
* constructor(@Optional() dependency:Dependency) {
* }
* }
* ```
*
* This directive would be instantiated with a `Dependency` directive found on the current element.
* If none can be
* found, the injector supplies `null` instead of throwing an error.
*
* ### Example
*
* Here we use a decorator directive to simply define basic tool-tip behavior.
*
* ```
* @Directive({
* selector: '[tooltip]',
* inputs: [
* 'text: tooltip'
* ],
* host: {
* '(mouseenter)': 'onMouseEnter()',
* '(mouseleave)': 'onMouseLeave()'
* }
* })
* class Tooltip{
* text:string;
* overlay:Overlay; // NOT YET IMPLEMENTED
* overlayManager:OverlayManager; // NOT YET IMPLEMENTED
*
* constructor(overlayManager:OverlayManager) {
* this.overlay = overlay;
* }
*
* onMouseEnter() {
* // exact signature to be determined
* this.overlay = this.overlayManager.open(text, ...);
* }
*
* onMouseLeave() {
* this.overlay.close();
* this.overlay = null;
* }
* }
* ```
* In our HTML template, we can then add this behavior to a `<div>` or any other element with the
* `tooltip` selector,
* like so:
*
* ```
* <div tooltip="some text here"></div>
* ```
*
* Directives can also control the instantiation, destruction, and positioning of inline template
* elements:
*
* A directive uses a {@link ViewContainerRef} to instantiate, insert, move, and destroy views at
* runtime.
* The {@link ViewContainerRef} is created as a result of `<template>` element, and represents a
* location in the current view
* where these actions are performed.
*
* Views are always created as children of the current {@link ViewMetadata}, and as siblings of the
* `<template>` element. Thus a
* directive in a child view cannot inject the directive that created it.
*
* Since directives that create views via ViewContainers are common in Angular, and using the full
* `<template>` element syntax is wordy, Angular
* also supports a shorthand notation: `<li *foo="bar">` and `<li template="foo: bar">` are
* equivalent.
*
* Thus,
*
* ```
* <ul>
* <li *foo="bar" title="text"></li>
* </ul>
* ```
*
* Expands in use to:
*
* ```
* <ul>
* <template [foo]="bar">
* <li title="text"></li>
* </template>
* </ul>
* ```
*
* Notice that although the shorthand places `*foo="bar"` within the `<li>` element, the binding for
* the directive
* controller is correctly instantiated on the `<template>` element rather than the `<li>` element.
*
* ## Lifecycle hooks
*
* When the directive class implements some {@link ../../guide/lifecycle-hooks.html} the callbacks
* are called by the change detection at defined points in time during the life of the directive.
*
* ### Example
*
* Let's suppose we want to implement the `unless` behavior, to conditionally include a template.
*
* Here is a simple directive that triggers on an `unless` selector:
*
* ```
* @Directive({
* selector: '[unless]',
* inputs: ['unless']
* })
* export class Unless {
* viewContainer: ViewContainerRef;
* templateRef: TemplateRef;
* prevCondition: boolean;
*
* constructor(viewContainer: ViewContainerRef, templateRef: TemplateRef) {
* this.viewContainer = viewContainer;
* this.templateRef = templateRef;
* this.prevCondition = null;
* }
*
* set unless(newCondition) {
* if (newCondition && (isBlank(this.prevCondition) || !this.prevCondition)) {
* this.prevCondition = true;
* this.viewContainer.clear();
* } else if (!newCondition && (isBlank(this.prevCondition) || this.prevCondition)) {
* this.prevCondition = false;
* this.viewContainer.create(this.templateRef);
* }
* }
* }
* ```
*
* We can then use this `unless` selector in a template:
* ```
* <ul>
* <li *unless="expr"></li>
* </ul>
* ```
*
* Once the directive instantiates the child view, the shorthand notation for the template expands
* and the result is:
*
* ```
* <ul>
* <template [unless]="exp">
* <li></li>
* </template>
* <li></li>
* </ul>
* ```
*
* Note also that although the `<li></li>` template still exists inside the `<template></template>`,
* the instantiated
* view occurs on the second `<li></li>` which is a sibling to the `<template>` element.

/**
* Declares an injectable parameter to be a live list of directives or variable
* bindings from the content children of a directive.
*
* ### Example ([live demo](http://plnkr.co/edit/lY9m8HLy7z06vDoUaSN2?p=preview))
*
* Assume that `<tabs>` component would like to get a list its children `<pane>`
* components as shown in this example:
*
* ```html
* <tabs>
* <pane title="Overview">...</pane>
* <pane *ngFor="let o of objects" [title]="o.title">{{o.text}}</pane>
* </tabs>
* ```
*
* The preferred solution is to query for `Pane` directives using this decorator.
*
* ```javascript
* @Component({
* selector: 'pane',
* inputs: ['title']
* })
* class Pane {
* title:string;
* }
*
* @Component({
* selector: 'tabs',
* template: `
* <ul>
* <li *ngFor="let pane of panes">{{pane.title}}</li>
* </ul>
* <ng-content></ng-content>
* `
* })
* class Tabs {
* panes: QueryList<Pane>;
* constructor(@Query(Pane) panes:QueryList<Pane>) {
* this.panes = panes;
* }
* }
* ```
*
* A query can look for variable bindings by passing in a string with desired binding symbol.
*
* ### Example ([live demo](http://plnkr.co/edit/sT2j25cH1dURAyBRCKx1?p=preview))
* ```html
* <seeker>
* <div #findme>...</div>
* </seeker>
*
* @Component({ selector: 'seeker' })
* class seeker {
* constructor(@Query('findme') elList: QueryList<ElementRef>) {...}
* }
* ```
*
* In this case the object that is injected depend on the type of the variable
* binding. It can be an ElementRef, a directive or a component.
*
* Passing in a comma separated list of variable bindings will query for all of them.
*
* ```html
* <seeker>
* <div #findMe>...</div>
* <div #findMeToo>...</div>
* </seeker>
*
* @Component({
* selector: 'seeker'
* })
* class Seeker {
* constructor(@Query('findMe, findMeToo') elList: QueryList<ElementRef>) {...}
* }
* ```
*
* Configure whether query looks for direct children or all descendants
* of the querying element, by using the `descendants` parameter.
* It is set to `false` by default.
*
* ### Example ([live demo](http://plnkr.co/edit/wtGeB977bv7qvA5FTYl9?p=preview))
* ```html
* <container #first>
* <item>a</item>
* <item>b</item>
* <container #second>
* <item>c</item>
* </container>
* </container>
* ```
*
* When querying for items, the first container will see only `a` and `b` by default,
* but with `Query(TextDirective, {descendants: true})` it will see `c` too.
*
* The queried directives are kept in a depth-first pre-order with respect to their
* positions in the DOM.
*
* Query does not look deep into any subcomponent views.
*
* Query is updated as part of the change-detection cycle. Since change detection
* happens after construction of a directive, QueryList will always be empty when observed in the
* constructor.
*
* The injected object is an unmodifiable live list.
* See {@link QueryList} for more details.

/**
* Declares an injectable parameter to be a live list of directives or variable
* bindings from the content children of a directive.
*
* ### Example ([live demo](http://plnkr.co/edit/lY9m8HLy7z06vDoUaSN2?p=preview))
*
* Assume that `<tabs>` component would like to get a list its children `<pane>`
* components as shown in this example:
*
* ```html
* <tabs>
* <pane title="Overview">...</pane>
* <pane *ngFor="let o of objects" [title]="o.title">{{o.text}}</pane>
* </tabs>
* ```
*
* The preferred solution is to query for `Pane` directives using this decorator.
*
* ```javascript
* @Component({
* selector: 'pane',
* inputs: ['title']
* })
* class Pane {
* title:string;
* }
*
* @Component({
* selector: 'tabs',
* template: `
* <ul>
* <li *ngFor="let pane of panes">{{pane.title}}</li>
* </ul>
* <ng-content></ng-content>
* `
* })
* class Tabs {
* panes: QueryList<Pane>;
* constructor(@Query(Pane) panes:QueryList<Pane>) {
* this.panes = panes;
* }
* }
* ```
*
* A query can look for variable bindings by passing in a string with desired binding symbol.
*
* ### Example ([live demo](http://plnkr.co/edit/sT2j25cH1dURAyBRCKx1?p=preview))
* ```html
* <seeker>
* <div #findme>...</div>
* </seeker>
*
* @Component({ selector: 'seeker' })
* class Seeker {
* constructor(@Query('findme') elList: QueryList<ElementRef>) {...}
* }
* ```
*
* In this case the object that is injected depend on the type of the variable
* binding. It can be an ElementRef, a directive or a component.
*
* Passing in a comma separated list of variable bindings will query for all of them.
*
* ```html
* <seeker>
* <div #find-me>...</div>
* <div #find-me-too>...</div>
* </seeker>
*
* @Component({
* selector: 'seeker'
* })
* class Seeker {
* constructor(@Query('findMe, findMeToo') elList: QueryList<ElementRef>) {...}
* }
* ```
*
* Configure whether query looks for direct children or all descendants
* of the querying element, by using the `descendants` parameter.
* It is set to `false` by default.
*
* ### Example ([live demo](http://plnkr.co/edit/wtGeB977bv7qvA5FTYl9?p=preview))
* ```html
* <container #first>
* <item>a</item>
* <item>b</item>
* <container #second>
* <item>c</item>
* </container>
* </container>
* ```
*
* When querying for items, the first container will see only `a` and `b` by default,
* but with `Query(TextDirective, {descendants: true})` it will see `c` too.
*
* The queried directives are kept in a depth-first pre-order with respect to their
* positions in the DOM.
*
* Query does not look deep into any subcomponent views.
*
* Query is updated as part of the change-detection cycle. Since change detection
* happens after construction of a directive, QueryList will always be empty when observed in the
* constructor.
*
* The injected object is an unmodifiable live list.
* See {@link QueryList} for more details.
