  4. * Converts a higher-order Observable into a first-order Observable by dropping
  5. * inner Observables while the previous inner Observable has not yet completed.

  12. * `exhaust` subscribes to an Observable that emits Observables, also known as a
  13. * higher-order Observable. Each time it observes one of these emitted inner
  14. * Observables, the output Observable begins emitting the items emitted by that
  15. * inner Observable. So far, it behaves like {@link mergeAll}. However,
  16. * `exhaust` ignores every new inner Observable if the previous Observable has
  17. * not yet completed. Once that one completes, it will accept and flatten the
  18. * next inner Observable and repeat this process.
  19. *
  20. * @example <caption>Run a finite timer for each click, only if there is no currently active timer</caption>
  21. * var clicks = Rx.Observable.fromEvent(document, 'click');
  22. * var higherOrder = clicks.map((ev) => Rx.Observable.interval(1000).take(5));
  23. * var result = higherOrder.exhaust();
  24. * result.subscribe(x => console.log(x));
