/**
|
|
* Branch out the source Observable values as a nested Observable starting from
|
|
* an emission from `openings` and ending when the output of `closingSelector`
|
|
* emits.
|
|
*
|
|
* <span class="informal">It's like {@link bufferToggle}, but emits a nested
|
|
* Observable instead of an array.</span>
|
|
*
|
|
* 
|
|
*
|
|
* Returns an Observable that emits windows of items it collects from the source
|
|
* Observable. The output Observable emits windows that contain those items
|
|
* emitted by the source Observable between the time when the `openings`
|
|
* Observable emits an item and when the Observable returned by
|
|
* `closingSelector` emits an item.
|
|
*
|
|
* ## Example
|
|
*
|
|
* Every other second, emit the click events from the next 500ms
|
|
*
|
|
* ```ts
|
|
* import { fromEvent, interval, windowToggle, EMPTY, mergeAll } from 'rxjs';
|
|
*
|
|
* const clicks = fromEvent(document, 'click');
|
|
* const openings = interval(1000);
|
|
* const result = clicks.pipe(
|
|
* windowToggle(openings, i => i % 2 ? interval(500) : EMPTY),
|
|
* mergeAll()
|
|
* );
|
|
* result.subscribe(x => console.log(x));
|
|
* ```

|
|
* @see {@link windowCount}
|

* @see {@link windowTime}
|
|
* @see {@link windowWhen}
|
|
* @see {@link bufferToggle}
|
|
*
|
|
* @param openings An observable of notifications to start new windows.
|
|
* @param closingSelector A function that takes the value emitted by the
|
|
* `openings` observable and returns an Observable, which, when it emits a next
|
|
* notification, signals that the associated window should complete.
|
|
* @return A function that returns an Observable of windows, which in turn are
|
|
* Observables.
