/**
* @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>

* 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>
* ```
