import { debounce as higherOrder } from '../operators/debounce'; /** * Emits a value from the source Observable only after a particular time span * determined by another Observable has passed without another source emission. * * It's like {@link debounceTime}, but the time span of * emission silence is determined by a second Observable. * * * * `debounce` 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 spawns a duration Observable by calling the * `durationSelector` function. The value is emitted only when the duration * Observable emits a value or completes, and if no other value was emitted on * the source Observable since the duration Observable was spawned. If a new * value appears before the duration Observable emits, the previous value will * be dropped and will not be emitted on the output Observable. * * Like {@link debounceTime}, this is a rate-limiting operator, and also a * delay-like operator since output emissions do not necessarily occur at the * same time as they did on the source Observable. * * @example Emit the most recent click after a burst of clicks * var clicks = Rx.Observable.fromEvent(document, 'click'); * var result = clicks.debounce(() => Rx.Observable.interval(1000)); * result.subscribe(x => console.log(x)); * * @see {@link audit} * @see {@link debounceTime} * @see {@link delayWhen} * @see {@link throttle} * * @param {function(value: T): SubscribableOrPromise} durationSelector A function * that receives a value from the source Observable, for computing the timeout * duration for each source value, returned as an Observable or a Promise. * @return {Observable} An Observable that delays the emissions of the source * Observable by the specified duration Observable returned by * `durationSelector`, and may drop some values if they occur too frequently. * @method debounce * @owner Observable */ export function debounce(durationSelector) { return higherOrder(durationSelector)(this); } //# sourceMappingURL=debounce.js.map
