Initially, the timer is disabled. As soon as the first source * value arrives, it is forwarded to the output Observable, and then the timer * is enabled. After `duration` milliseconds (or the time unit determined * internally by the optional `scheduler`) has passed, the timer is disabled, * and this process repeats for the next source value. Optionally takes a * {@link IScheduler} for managing timers. * * @example Emit clicks at a rate of at most one click per second * var clicks = Rx.Observable.fromEvent(document, 'click'); * var result = clicks.throttleTime(1000); * result.subscribe(x => console.log(x)); * * @see {@link auditTime} * @see {@link debounceTime} * @see {@link delay} * @see {@link sampleTime} * @see {@link throttle} * * @param {number} duration Time to wait before emitting another value after * emitting the last value, measured 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 throttling. * @return {Observable} An Observable that performs the throttle operation to * limit the rate of emissions from the source. * @method throttleTime * @owner Observable */ export function throttleTime(duration, scheduler = async, config = defaultThrottleConfig) { return higherOrder(duration, scheduler, config)(this); } //# sourceMappingURL=throttleTime.js.map
