- * Branch out the source Observable values as a nested Observable periodically
- * in time.
- *
- * <span class="informal">It's like {@link bufferTime}, but emits a nested
- * Observable instead of an array.</span>
- *
- * <img src="./img/windowTime.png" width="100%">
- *
- * Returns an Observable that emits windows of items it collects from the source
- * Observable. The output Observable starts a new window periodically, as
- * determined by the `windowCreationInterval` argument. It emits each window
- * after a fixed timespan, specified by the `windowTimeSpan` argument. When the
- * source Observable completes or encounters an error, the output Observable
- * emits the current window and propagates the notification from the source
- * Observable. If `windowCreationInterval` is not provided, the output
- * Observable starts a new window when the previous window of duration
- * `windowTimeSpan` completes. If `maxWindowCount` is provided, each window
- * will emit at most fixed number of values. Window will complete immediately
- * after emitting last value and next one still will open as specified by
- * `windowTimeSpan` and `windowCreationInterval` arguments.
- *
- * @example <caption>In every window of 1 second each, emit at most 2 click events</caption>
- * var clicks = Rx.Observable.fromEvent(document, 'click');
- * var result = clicks.windowTime(1000)
- * .map(win => win.take(2)) // each window has at most 2 emissions
- * .mergeAll(); // flatten the Observable-of-Observables
- * result.subscribe(x => console.log(x));
- *
- * @example <caption>Every 5 seconds start a window 1 second long, and emit at most 2 click events per window</caption>
- * var clicks = Rx.Observable.fromEvent(document, 'click');
- * var result = clicks.windowTime(1000, 5000)
- * .map(win => win.take(2)) // each window has at most 2 emissions
- * .mergeAll(); // flatten the Observable-of-Observables
- * result.subscribe(x => console.log(x));
- *
- * @example <caption>Same as example above but with maxWindowCount instead of take</caption>
- * var clicks = Rx.Observable.fromEvent(document, 'click');
- * var result = clicks.windowTime(1000, 5000, 2) // each window has still at most 2 emissions
- * .mergeAll(); // flatten the Observable-of-Observables
- * result.subscribe(x => console.log(x));
