* Ignores source values for `duration` milliseconds, then emits the most recent
|
||
|
|
* value from the source Observable, then repeats this process.
|
||
|
|
*
|
||
|
|
* <span class="informal">When it sees a source value, it ignores that plus
|
||
|
|
* the next ones for `duration` milliseconds, and then it emits the most recent
|

|

|

|
|
* `auditTime` is similar to `throttleTime`, but emits the last value from the
|
||
|
|
* silenced time window, instead of the first value. `auditTime` emits the most
|
||
|
|
* recent value from the source Observable on the output Observable as soon as
|
||
|
|
* its internal timer becomes disabled, and ignores source values while the
|
||
|
|
* timer is enabled. Initially, the timer is disabled. As soon as the first
|
||
|
|
* source value arrives, the timer is enabled. After `duration` milliseconds (or
|
||
|
|
* the time unit determined internally by the optional `scheduler`) has passed,
|
||
|
|
* the timer is disabled, then the most recent source value is emitted on the
|
||
|
|
* output Observable, and this process repeats for the next source value.
|
||
|
|
* Optionally takes a {@link SchedulerLike} for managing timers.
|
||
|
|

|
||
|
|
* ## Example
|
||
|
|
*
|
||
|
|
* Emit clicks at a rate of at most one click per second
|
||
|
|
* ```ts
|
||
|
|
* import { fromEvent } from 'rxjs';
|
||
|
|
* import { auditTime } from 'rxjs/operators';
|
||
|
|
*
|
||
|
|
* const clicks = fromEvent(document, 'click');
|
||
|
|
* const result = clicks.pipe(auditTime(1000));
|
||
|
|
* result.subscribe(x => console.log(x));
|
||
|
|
* ```

* @see {@link audit}
|
||
|
|
* @see {@link debounceTime}
|
||
|
|
* @see {@link delay}
|
||
|
|
* @see {@link sampleTime}
|
||
|
|
* @see {@link throttleTime}
|
||
|
|
*
|
||
|
|
* @param {number} duration Time to wait before emitting the most recent source
|
||
|
|
* value, measured in milliseconds or the time unit determined internally
|
||
|
|
* by the optional `scheduler`.
|
||
|
|
* @param {SchedulerLike} [scheduler=async] The {@link SchedulerLike} to use for
|
||
|
|
* managing the timers that handle the rate-limiting behavior.
|
||
|
|
* @return {Observable<T>} An Observable that performs rate-limiting of
|
||
|
|
* emissions from the source Observable.
|
||
|
|
* @method auditTime
|
||
|
|
* @owner Observable
