* A configuration object that defines a single route.

*
* Supports static, parameterized, redirect, and wildcard routes, as well as
* custom route data and resolve methods.
*
* For detailed usage information, see the [Routing Guide](guide/routing/common-router-tasks).
*
* @usageNotes
*
* ### Simple Configuration
*
* The following route specifies that when navigating to, for example,
* `/team/11/user/bob`, the router creates the 'Team' component
* with the 'User' child component in it.
*
* ```
* [{
* path: 'team/:id',
* component: Team,
* children: [{
* path: 'user/:name',
* component: User
* }]
* }]
* ```
*
* ### Multiple Outlets
*
* The following route creates sibling components with multiple outlets.
* When navigating to `/team/11(aux:chat/jim)`, the router creates the 'Team' component next to
* the 'Chat' component. The 'Chat' component is placed into the 'aux' outlet.
*
* ```
* [{
* path: 'team/:id',
* component: Team
* }, {
* path: 'chat/:user',
* component: Chat
* outlet: 'aux'
* }]
* ```
*
* ### Wild Cards
*
* The following route uses wild-card notation to specify a component
* that is always instantiated regardless of where you navigate to.
*
* ```
* [{
* path: '**',
* component: WildcardComponent
* }]
* ```
*
* ### Redirects
*
* The following route uses the `redirectTo` property to ignore a segment of
* a given URL when looking for a child path.
*
* When navigating to '/team/11/legacy/user/jim', the router changes the URL segment
* '/team/11/legacy/user/jim' to '/team/11/user/jim', and then instantiates
* the Team component with the User child component in it.
*
* ```
* [{
* path: 'team/:id',
* component: Team,
* children: [{
* path: 'legacy/user/:name',
* redirectTo: 'user/:name'
* }, {
* path: 'user/:name',
* component: User
* }]
* }]
* ```
*
* The redirect path can be relative, as shown in this example, or absolute.
* If we change the `redirectTo` value in the example to the absolute URL segment '/user/:name',
* the result URL is also absolute, '/user/jim'.
* ### Empty Path
*
* Empty-path route configurations can be used to instantiate components that do not 'consume'
* any URL segments.
*
* In the following configuration, when navigating to
* `/team/11`, the router instantiates the 'AllUsers' component.
*
* ```
* [{
* path: 'team/:id',
* component: Team,
* children: [{
* path: '',
* component: AllUsers
* }, {
* path: 'user/:name',
* component: User
* }]
* }]
* ```
*
* Empty-path routes can have children. In the following example, when navigating
* to `/team/11/user/jim`, the router instantiates the wrapper component with
* the user component in it.
*
* Note that an empty path route inherits its parent's parameters and data.
*
* ```
* [{
* path: 'team/:id',
* component: Team,
* children: [{
* path: '',
* component: WrapperCmp,
* children: [{
* path: 'user/:name',
* component: User
* }]
* }]
* }]
* ```
*
* ### Matching Strategy
*
* The default path-match strategy is 'prefix', which means that the router
* checks URL elements from the left to see if the URL matches a specified path.
* For example, '/team/11/user' matches 'team/:id'.
*
* ```
* [{
* path: '',
* pathMatch: 'prefix', //default
* redirectTo: 'main'
* }, {
* path: 'main',
* component: Main
* }]
* ```
*
* You can specify the path-match strategy 'full' to make sure that the path
* covers the whole unconsumed URL. It is important to do this when redirecting
* empty-path routes. Otherwise, because an empty path is a prefix of any URL,
* the router would apply the redirect even when navigating to the redirect destination,
* creating an endless loop.
*
* In the following example, supplying the 'full' `pathMatch` strategy ensures
* that the router applies the redirect if and only if navigating to '/'.
*
* ```
* [{
* path: '',
* pathMatch: 'full',
* redirectTo: 'main'
* }, {
* path: 'main',
* component: Main
* }]
* ```
*
* ### Componentless Routes
*
* You can share parameters between sibling components.
* For example, suppose that two sibling components should go next to each other,
* and both of them require an ID parameter. You can accomplish this using a route
* that does not specify a component at the top level.
*
* In the following example, 'MainChild' and 'AuxChild' are siblings.
* When navigating to 'parent/10/(a//aux:b)', the route instantiates
* the main child and aux child components next to each other.
* For this to work, the application component must have the primary and aux outlets defined.
*
* ```
* [{
* path: 'parent/:id',
* children: [
* { path: 'a', component: MainChild },
* { path: 'b', component: AuxChild, outlet: 'aux' }
* ]
* }]
* ```
*
* The router merges the parameters, data, and resolve of the componentless
* parent into the parameters, data, and resolve of the children.
*
* This is especially useful when child components are defined
* with an empty path string, as in the following example.
* With this configuration, navigating to '/parent/10' creates
* the main child and aux components.
*
* ```
* [{
* path: 'parent/:id',
* children: [
* { path: '', component: MainChild },
* { path: '', component: AuxChild, outlet: 'aux' }
* ]
* }]
* ```
*
* ### Lazy Loading
*
* Lazy loading speeds up application load time by splitting the application
* into multiple bundles and loading them on demand.
* To use lazy loading, provide the `loadChildren` property in the `Route` object,
* instead of the `children` property.
*
* Given the following example route, the router will lazy load
* the associated module on demand using the browser native import system.
*
* ```
* [{
* path: 'lazy',
* loadChildren: () => import('./lazy-route/lazy.module').then(mod => mod.LazyModule),
* }];
* ```

/**
* @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 `` locations on the page.
*
* Given a route configuration `[{ path: 'user/:name', component: UserCmp }]`,
* the following creates a static link to the route:
* `link to user component`
*
* 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 segments.
* 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 `Jim` creates the URL
* `/user/(jim//aux:team)`.
* See {@link Router#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:
*
* ```
*
* link to user component
*
* ```
* 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:
*
* ```
*
* link to user component
*
* ```
*
* `queryParams`, `fragment`, `queryParamsHandling`, `preserveFragment`, and `relativeTo`
* cannot be used when the `routerLink` input is a `UrlTree`.
*
* See {@link 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:
*
* ```
*
* link to user component
*
* ```
*
* Use {@link 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:
*
* ```
* Bob
* ```
*
* 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:
*
* ```
* Bob
* Bob
* ```
*
* To add the classes only when the URL matches the link exactly, add the option `exact: true`:
*
* ```
* Bob
* ```
*
* 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:
*
* ```
*
* Bob {{ rla.isActive ? '(already open)' : ''}}
*
* ```
*
* You can apply the `RouterLinkActive` directive to an ancestor of linked elements.
* For example, the following sets the active-link class on the `` parent tag
* when the URL is either '/user/jim' or '/user/bob'.
*
* ```
*
* ```
*
* The `RouterLinkActive` directive can also be used to set the aria-current attribute
* to provide an alternative distinction for active elements to visually impaired users.
*
* For example, the following code adds the 'active' class to the Home Page link when it is
* indeed active and in such case also sets its aria-current attribute to 'page':
*
* ```

* Represents the parsed URL.
*
* Since a router state is a tree, and the URL is nothing but a serialized state, the URL is a
* serialized tree.
* UrlTree is a data structure that provides a lot of affordances in dealing with URLs
*
* @usageNotes
* ### Example
*
* ```
* @Component({templateUrl:'template.html'})
* class MyComponent {
* constructor(router: Router) {
* const tree: UrlTree =
* router.parseUrl('/team/33/(user/victor//support:help)?debug=true#fragment');
* const f = tree.fragment; // return 'fragment'
* const q = tree.queryParams; // returns {debug: 'true'}
* const g: UrlSegmentGroup = tree.root.children[PRIMARY_OUTLET];
* const s: UrlSegment[] = g.segments; // returns 2 segments 'team' and '33'
* g.children[PRIMARY_OUTLET].segments; // returns 2 segments 'user' and 'victor'
* g.children['support'].segments; // return 1 segment 'help'
* }
* }
* ```
