/** |
|
* 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 |
|
* Observable `windowBoundaries` emits an item. Because each window is an |
|
* Observable, the output is a higher-order Observable. |
|
* |
|
* @example <caption>In every window of 1 second each, emit at most 2 click events</caption> |
|
* var clicks = Rx.Observable.fromEvent(document, 'click'); |
|
* var interval = Rx.Observable.interval(1000); |
|
* var result = clicks.window(interval) |
|
* .map(win => win.take(2)) // each window has at most 2 emissions |
|
* .mergeAll(); // flatten the Observable-of-Observables |
|
* result.subscribe(x => console.log(x)); |
