|
* Creates an output Observable which sequentially emits all values from every
|
|
* given input Observable after the current Observable.
|
|
*
|
|
* <span class="informal">Concatenates multiple Observables together by
|
|
* sequentially emitting their values, one Observable after the other.</span>

* <img src="./img/concat.png" width="100%">
|
|
*
|
|
* Joins this Observable with multiple other Observables by subscribing to them
|
|
* one at a time, starting with the source, and merging their results into the
|
|
* output Observable. Will wait for each Observable to complete before moving
|
|
* on to the next.
|
|
*
|
|
* @example <caption>Concatenate a timer counting from 0 to 3 with a synchronous sequence from 1 to 10</caption>
|
|
* var timer = Rx.Observable.interval(1000).take(4);
|
|
* var sequence = Rx.Observable.range(1, 10);
|
|
* var result = timer.concat(sequence);
|
|
* result.subscribe(x => console.log(x));
|
|
*
|
|
* // results in:
|
|
* // 1000ms-> 0 -1000ms-> 1 -1000ms-> 2 -1000ms-> 3 -immediate-> 1 ... 10
|
|
*
|
|
* @example <caption>Concatenate 3 Observables</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 result = timer1.concat(timer2, timer3);
|
|
* result.subscribe(x => console.log(x));
|
|
*
|
|
* // results in the following:
|
|
* // (Prints to console sequentially)
|
|
* // -1000ms-> 0 -1000ms-> 1 -1000ms-> ... 9
|
|
* // -2000ms-> 0 -2000ms-> 1 -2000ms-> ... 5
|
|
* // -500ms-> 0 -500ms-> 1 -500ms-> ... 9
