- * 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
