- * Branch out the source Observable values as a nested Observable whenever
- * `windowBoundaries` emits.
- *
- * <span class="informal">It's like {@link buffer}, 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 connected, non-overlapping
- * windows. It emits the current window and opens a new one whenever the
- * `windowBoundaries` emits an item. `windowBoundaries` can be any type that
- * `ObservableInput` accepts. It internally gets converted to an Observable.
- * Because each window is an Observable, the output is a higher-order Observable.
- *
- * ## Example
- *
- * In every window of 1 second each, emit at most 2 click events
- *
- * ```ts
- * import { fromEvent, interval, window, map, take, mergeAll } from 'rxjs';
- *
- * const clicks = fromEvent(document, 'click');
- * const sec = interval(1000);
- * const result = clicks.pipe(
- * window(sec),
- * map(win => win.pipe(take(2))), // take at most 2 emissions from each window
- * mergeAll() // flatten the Observable-of-Observables
- * );
- * result.subscribe(x => console.log(x));
- * ```
- *
- * @see {@link windowCount}
- * @see {@link windowTime}
- * @see {@link windowToggle}
- * @see {@link windowWhen}
- * @see {@link buffer}
- *
- * @param windowBoundaries An `ObservableInput` that completes the
- * previous window and starts a new window.
- * @return A function that returns an Observable of windows, which are
- * Observables emitting values of the source Observable.
