|
|
* Creates an output Observable which concurrently emits all values from every
|
||
|
|
* given input Observable.
|
||
|
|
*
|
||
|
|
* <span class="informal">Flattens multiple Observables together by blending
|
||
|
|
* their values into one Observable.</span>

|
*
|
||
|
|
* `merge` subscribes to each given input Observable (either the source or an
|
||
|
|
* Observable given as argument), and simply forwards (without doing any
|
||
|
|
* transformation) all the values from all the input Observables to the output
|
||
|
|
* Observable. The output Observable only completes once all input Observables
|
||
|
|
* have completed. Any error delivered by an input Observable will be immediately
|
||
|
|
* emitted on the output Observable.
|
||
|
|
*
|
||
|
|
* @example <caption>Merge together two Observables: 1s interval and clicks</caption>
|
||
|
|
* var clicks = Rx.Observable.fromEvent(document, 'click');
|
||
|
|
* var timer = Rx.Observable.interval(1000);
|
||
|
|
* var clicksOrTimer = clicks.merge(timer);
|
||
|
|
* clicksOrTimer.subscribe(x => console.log(x));
|
||
|
|
*
|
||
|
|
* @example <caption>Merge together 3 Observables, but only 2 run concurrently</caption>
|
||
|
|
* var timer1 = Rx.Observable.interval(1000).take(10);
|
||
|
|
* var timer2 = Rx.Observable.interval(2000).take(6);
|
||
|
|
* var timer3 = Rx.Observable.interval(500).take(10);
|
||
|
|
* var concurrent = 2; // the argument
|
||
|
|
* var merged = timer1.merge(timer2, timer3, concurrent);
|
||
|
|
* merged.subscribe(x => console.log(x));
