- *
- * `sampleTime` periodically looks at the source Observable and emits whichever
- * value it has most recently emitted since the previous sampling, unless the
- * source has not emitted anything since the previous sampling. The sampling
- * happens periodically in time every `period` milliseconds (or the time unit
- * defined by the optional `scheduler` argument). The sampling starts as soon as
- * the output Observable is subscribed.
- *
- * @example <caption>Every second, emit the most recent click at most once</caption>
- * var clicks = Rx.Observable.fromEvent(document, 'click');
- * var result = clicks.sampleTime(1000);
- * result.subscribe(x => console.log(x));

- * @see {@link debounceTime}

- * @see {@link throttleTime}
- *
- * @param {number} period The sampling period expressed in milliseconds or the
- * time unit determined internally by the optional `scheduler`.
- * @param {Scheduler} [scheduler=async] The {@link IScheduler} to use for
- * managing the timers that handle the sampling.
- * @return {Observable<T>} An Observable that emits the results of sampling the
- * values emitted by the source Observable at the specified time interval.
