This operator keeps track of the most recent value from the * source Observable, and emits that only when `dueTime` enough time has passed * without any other value appearing on the source Observable. If a new value * appears before `dueTime` silence occurs, the previous value will be dropped * and will not be emitted on the output Observable. * * This is a rate-limiting operator, because it is impossible for more than one * value to be emitted in any time window of duration `dueTime`, but it is also * a delay-like operator since output emissions do not occur at the same time as * they did on the source Observable. Optionally takes a {@link IScheduler} for * managing timers. * * @example Emit the most recent click after a burst of clicks * var clicks = Rx.Observable.fromEvent(document, 'click'); * var result = clicks.debounceTime(1000); * result.subscribe(x => console.log(x)); * * @see {@link auditTime} * @see {@link debounce} * @see {@link delay} * @see {@link sampleTime} * @see {@link throttleTime} * * @param {number} dueTime The timeout duration in milliseconds (or the time * unit determined internally by the optional `scheduler`) for the window of * time required to wait for emission silence before emitting the most recent * source value. * @param {Scheduler} [scheduler=async] The {@link IScheduler} to use for * managing the timers that handle the timeout for each value. * @return {Observable} An Observable that delays the emissions of the source * Observable by the specified `dueTime`, and may drop some values if they occur * too frequently. * @method debounceTime * @owner Observable */ export function debounceTime(dueTime, scheduler = async) { return higherOrder(dueTime, scheduler)(this); } //# sourceMappingURL=debounceTime.js.map
