      interface UrlTree {
  root: UrlSegmentGroup
  queryParams: Params
  fragment: string | null
  queryParamMap: ParamMap
  toString(): string
}

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' } }
      
      
  1. @Component({templateUrl:'template.html'})
  2. class MyComponent {
  3.   constructor(router: Router) {
  4.     const tree: UrlTree =
  5.       router.parseUrl('/team/33/(user/victor//support:help)?debug=true#fragment');
  6.     const f = tree.fragment; // return 'fragment'
  7.     const q = tree.queryParams; // returns {debug: 'true'}
  8.     const g: UrlSegmentGroup = tree.root.children[PRIMARY_OUTLET];
  9.     const s: UrlSegment[] = g.segments; // returns 2 segments 'team' and '33'
  10.     g.children[PRIMARY_OUTLET].segments; // returns 2 segments 'user' and 'victor'
  11.     g.children['support'].segments; // return 1 segment 'help'
  12.   }
