- * Emits the most recently emitted value from the source Observable within
- * periodic time intervals.
- *
- * <span class="informal">Samples the source Observable at periodic time
- * intervals, emitting what it samples.</span>
- *
- * 
- *
- * `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
- *
- * Every second, emit the most recent click at most once
- *
- * ```ts
- * import { fromEvent, sampleTime } from 'rxjs';
- *
- * const clicks = fromEvent(document, 'click');
- * const result = clicks.pipe(sampleTime(1000));
- *
- * result.subscribe(x => console.log(x));
- * ```
- *
- * @see {@link auditTime}
- * @see {@link debounceTime}
- * @see {@link delay}
- * @see {@link sample}
- * @see {@link throttleTime}
- *
- * @param period The sampling period expressed in milliseconds or the time unit
- * determined internally by the optional `scheduler`.
- * @param scheduler The {@link SchedulerLike} to use for managing the timers
- * that handle the sampling.
- * @return A function that returns an Observable that emits the results of
- * sampling the values emitted by the source Observable at the specified time
- * interval.
