|
* Converts a higher-order Observable into a first-order Observable by |
|
* concatenating the inner Observables in order. |
|
* |
|
* <span class="informal">Flattens an Observable-of-Observables by putting one |
|
* inner Observable after the other.</span> |
|
* |
|
* <img src="./img/concatAll.png" width="100%"> |
|
* |
|
* Joins every Observable emitted by the source (a higher-order Observable), in |
|
* a serial fashion. It subscribes to each inner Observable only after the |
|
* previous inner Observable has completed, and merges all of their values into |
|
* the returned observable. |
|
* |
|
* __Warning:__ If the source Observable emits Observables quickly and |
|
* endlessly, and the inner Observables it emits generally complete slower than |
|
* the source emits, you can run into memory issues as the incoming Observables |
|
* collect in an unbounded buffer. |
|
* |
|
* Note: `concatAll` is equivalent to `mergeAll` with concurrency parameter set |
|
* to `1`. |
|
* |
|
* @example <caption>For each click event, tick every second from 0 to 3, with no concurrency</caption> |
|
* var clicks = Rx.Observable.fromEvent(document, 'click'); |
|
* var higherOrder = clicks.map(ev => Rx.Observable.interval(1000).take(4)); |
|
* var firstOrder = higherOrder.concatAll(); |
|
* firstOrder.subscribe(x => console.log(x)); |
|
* |
|
* // Results in the following: |
|
* // (results are not concurrent) |
|
* // For every click on the "document" it will emit values 0 to 3 spaced |
|
* // on a 1000ms interval |
|
* // one click = 1000ms-> 0 -1000ms-> 1 -1000ms-> 2 -1000ms-> 3 |
