/** |
|
* Returns an Observable that mirrors the source Observable with the exception of a `complete`. If the source |
|
* Observable calls `complete`, this method will emit to the Observable returned from `notifier`. If that Observable |
|
* calls `complete` or `error`, then this method will call `complete` or `error` on the child subscription. Otherwise |
|
* this method will resubscribe to the source Observable. |
|
* |
|
*  |
|
* |
|
* ## Example |
|
* Repeat a message stream on click |
|
* ```ts |
|
* import { of, fromEvent } from 'rxjs'; |
|
* import { repeatWhen } from 'rxjs/operators'; |
|
* |
|
* const source = of('Repeat message'); |
|
* const documentClick$ = fromEvent(document, 'click'); |
|
* |
|
* source.pipe(repeatWhen(() => documentClick$) |
|
* ).subscribe(data => console.log(data)) |
|
* ``` |
|
* @see {@link repeat} |
|
* @see {@link retry} |
|
* @see {@link retryWhen} |
|
* |
|
* @param {function(notifications: Observable): Observable} notifier - Receives an Observable of notifications with |
|
* which a user can `complete` or `error`, aborting the repetition. |
|
* @return {Observable} The source Observable modified with repeat logic. |
|
* @method repeatWhen |
