| /** |
| * Emits a value from the source Observable only after a particular time span |
| * has passed without another source emission. |
| * |
| * <span class="informal">It's like {@link delay}, but passes only the most |
| * recent value from each burst of emissions.</span> |
| * |
| *  |
| * |
| * `debounceTime` delays values emitted by the source Observable, but drops |
| * previous pending delayed emissions if a new value arrives on the source |
| * Observable. 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 SchedulerLike} for |
| * managing timers. |
| * |
| * ## Example |
| * Emit the most recent click after a burst of clicks |
| * ```ts |
| * import { fromEvent } from 'rxjs'; |
| * import { debounceTime } from 'rxjs/operators'; |
| * |
| * const clicks = fromEvent(document, 'click'); |
| * const result = clicks.pipe(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 {SchedulerLike} [scheduler=async] The {@link SchedulerLike} 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 |
