/**
* \@description
*
* Lets you link to specific routes in your app.
*
* Consider the following route configuration:
* `[{ path: 'user/:name', component: UserCmp }]`.
* When linking to this `user/:name` route, you use the `RouterLink` directive.
*
* If the link is static, you can use the directive as follows:
* `<a routerLink="/user/bob">link to user component</a>`
*
* If you use dynamic values to generate the link, you can pass an array of path
* segments, followed by the params for each segment.
*
* For instance `['/team', teamId, 'user', userName, {details: true}]`
* means that we want to generate a link to `/team/11/user/bob;details=true`.
*
* Multiple static segments can be merged into one
* (e.g., `['/team/11/user', userName, {details: true}]`).
*
* The first segment name can be prepended with `/`, `./`, or `../`:
* * If the first segment begins with `/`, the router will look up the route from the root of the
* app.
* * If the first segment begins with `./`, or doesn't begin with a slash, the router will
* instead look in the children of the current activated route.
* * And if the first segment begins with `../`, the router will go up one level.
*
* You can set query params and fragment as follows:
*
* ```
* <a [routerLink]="['/user/bob']" [queryParams]="{debug: true}" fragment="education">
* link to user component
* </a>
* ```
* RouterLink will use these to generate this link: `/user/bob#education?debug=true`.
*
* (Deprecated in v4.0.0 use `queryParamsHandling` instead) You can also tell the
* directive to preserve the current query params and fragment:
*
* ```
* <a [routerLink]="['/user/bob']" preserveQueryParams preserveFragment>
* link to user component
* </a>
* ```
*
* You can tell the directive how to handle queryParams. Available options are:
* - `'merge'`: merge the queryParams into the current queryParams
* - `'preserve'`: preserve the current queryParams
* - default/`''`: use the queryParams only
*
* Same options for {\@link NavigationExtras#queryParamsHandling
* NavigationExtras#queryParamsHandling}.
*
* ```
* <a [routerLink]="['/user/bob']" [queryParams]="{debug: true}" queryParamsHandling="merge">
* link to user component
* </a>
* ```
*
* You can provide a `state` value to be persisted to the browser's History.state
* property (See https://developer.mozilla.org/en-US/docs/Web/API/History#Properties). It's
* used as follows:
*
* ```
* <a [routerLink]="['/user/bob']" [state]="{tracingId: 123}">
* link to user component
* </a>
* ```
*
* And later the value can be read from the router through `router.getCurrentNavigation`.
* For example, to capture the `tracingId` above 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});
* });
* ```
*
* The router link directive always treats the provided input as a delta to the current url.
*
* For instance, if the current url is `/user/(box//aux:team)`.
*
* Then the following link `<a [routerLink]="['/user/jim']">Jim</a>` will generate the link
* `/user/(jim//aux:team)`.
*
* See {\@link Router#createUrlTree createUrlTree} for more information.

* Lets you add a CSS class to an element when the link's route becomes active.
*
* This directive lets you add a CSS class to an element when the link's route
* becomes active.
*
* Consider the following example:
*
* ```
* <a routerLink="/user/bob" routerLinkActive="active-link">Bob</a>
* ```
*
* When the url is either '/user' or '/user/bob', the active-link class will
* be added to the `a` tag. If the url changes, the class will be removed.
*
* You can set more than one class, as follows:
*
* ```
* <a routerLink="/user/bob" routerLinkActive="class1 class2">Bob</a>
* <a routerLink="/user/bob" [routerLinkActive]="['class1', 'class2']">Bob</a>
* ```
*
* You can configure RouterLinkActive by passing `exact: true`. This will add the classes
* only when the url matches the link exactly.
*
* ```
* <a routerLink="/user/bob" routerLinkActive="active-link" [routerLinkActiveOptions]="{exact:
* true}">Bob</a>
* ```
*
* You can assign the RouterLinkActive instance to a template variable and directly check
* the `isActive` status.
* ```
* <a routerLink="/user/bob" routerLinkActive #rla="routerLinkActive">
* Bob {{ rla.isActive ? '(already open)' : ''}}
* </a>
* ```
*
* Finally, you can apply the RouterLinkActive directive to an ancestor of a RouterLink.
*
* ```
* <div routerLinkActive="active-link" [routerLinkActiveOptions]="{exact: true}">
* <a routerLink="/user/jim">Jim</a>
* <a routerLink="/user/bob">Bob</a>
* </div>
* ```
*
* This will set the active-link class on the div tag if the url is either '/user/jim' or
* '/user/bob'.

*
* Adds router directives and providers.
*
* Managing state transitions is one of the hardest parts of building applications. This is
* especially true on the web, where you also need to ensure that the state is reflected in the URL.
* In addition, we often want to split applications into multiple bundles and load them on demand.
* Doing this transparently is not trivial.
*
* The Angular router solves these problems. Using the router, you can declaratively specify
* application states, manage state transitions while taking care of the URL, and load bundles on
* demand.
*
* [Read this developer guide](https://angular.io/docs/ts/latest/guide/router.html) to get an
* overview of how the router should be used.

*
* * `enableTracing` Toggles whether the router should log all navigation events to the console.
* * `useHash` Enables the location strategy that uses the URL fragment instead of the history
* API.
* * `initialNavigation` Disables the initial navigation.
* * `errorHandler` Defines a custom error handler for failed navigations.
* * `preloadingStrategy` Configures a preloading strategy. See `PreloadAllModules`.
* * `onSameUrlNavigation` Define what the router should do if it receives a navigation request to
* the current URL.
* * `scrollPositionRestoration` Configures if the scroll position needs to be restored when
* navigating back.
* * `anchorScrolling` Configures if the router should scroll to the element when the url has a
* fragment.
* * `scrollOffset` Configures the scroll offset the router will use when scrolling to an element.
* * `paramsInheritanceStrategy` Defines how the router merges params, data and resolved data from
* parent to child routes.
* * `malformedUriErrorHandler` Defines a custom malformed uri error handler function. This
* handler is invoked when encodedURI contains invalid character sequences.
* * `urlUpdateStrategy` Defines when the router updates the browser URL. The default behavior is
* to update after successful navigation.
* * `relativeLinkResolution` Enables the correct relative link resolution in components with
* empty paths.
*
* See `ExtraOptions` for more details about the above options.
