The ActivatedRouteSnapshot to apply the commands to

@paramcommandsreadonly any[]

An array of URL fragments with which to construct the new URL tree. If the path is static, can be the literal URL string. For a dynamic path, pass an array of path segments, followed by the parameters for each segment. The fragments are applied to the one provided in the relativeTo parameter.

@paramqueryParamsParams | null

The query parameters for the UrlTree. null if the UrlTree does not have any query parameters.

@paramfragmentstring | null

The fragment for the UrlTree. null if the UrlTree does not have a fragment.

Usage Notes

// create /team/33/user/11createUrlTreeFromSnapshot(snapshot, ['/team', 33, 'user', 11]);// create /team/33;expand=true/user/11createUrlTreeFromSnapshot(snapshot, ['/team', 33, {expand: true}, 'user', 11]);// you can collapse static segments like this (this works only with the first passed-in value):createUrlTreeFromSnapshot(snapshot, ['/team/33/user', userId]);// If the first segment can contain slashes, and you do not want the router to split it,// you can do the following:createUrlTreeFromSnapshot(snapshot, [{segmentPath: '/one/two'}]);// create /team/33/(user/11//right:chat)createUrlTreeFromSnapshot(snapshot, ['/team', 33, {outlets: {primary: 'user/11', right:'chat'}}], null, null);// remove the right secondary nodecreateUrlTreeFromSnapshot(snapshot, ['/team', 33, {outlets: {primary: 'user/11', right: null}}]);// For the examples below, assume the current URL is for the `/team/33/user/11` and the`ActivatedRouteSnapshot` points to `user/11`:// navigate to /team/33/user/11/detailscreateUrlTreeFromSnapshot(snapshot, ['details']);// navigate to /team/33/user/22createUrlTreeFromSnapshot(snapshot, ['../22']);// navigate to /team/44/user/22createUrlTreeFromSnapshot(snapshot, ['../../team/44/user/22']);
