 /**
  * A directive that works with the [Router] and loads the template associated
  * with the current route.
  *
  *     <ng-view></ng-view>
  *
  * [NgViewDirective] can work with [NgViewDirective] to define nested views
  * for hierarchical routes. For example:
  *
- *     void initRoutes(Router router, ViewFactory view) {
- *       router.root
- *         ..addRoute(
- *             name: 'library',
- *             path: '/library',
- *             enter: view('library.html'),
- *             mount: (Route route) => route
- *               ..addRoute(
- *                   name: 'all',
- *                   path: '/all',
- *                   enter: view('book_list.html'))
- *               ..addRoute(
- *                   name: 'book',
- *                   path: '/:bookId',
- *                   mount: (Route route) => route
- *                     ..addRoute(
- *                         name: 'overview',
- *                         path: '/overview',
- *                         defaultRoute: true,
- *                         enter: view('book_overview.html'))
- *                     ..addRoute(
- *                         name: 'read',
- *                         path: '/read',
- *                         enter: view('book_read.html'))));
+ *     class MyRouteInitializer implements RouteInitializer {
+ *       void init(Router router, ViewFactory view) {
