import { windowCount as higherOrder } from '../operators/windowCount'; /** * Branch out the source Observable values as a nested Observable with each * nested Observable emitting at most `windowSize` values. * * It's like {@link bufferCount}, but emits a nested * Observable instead of an array. * * * * Returns an Observable that emits windows of items it collects from the source * Observable. The output Observable emits windows every `startWindowEvery` * items, each containing no more than `windowSize` items. When the source * Observable completes or encounters an error, the output Observable emits * the current window and propagates the notification from the source * Observable. If `startWindowEvery` is not provided, then new windows are * started immediately at the start of the source and when each window completes * with size `windowSize`. * * @example Ignore every 3rd click event, starting from the first one * var clicks = Rx.Observable.fromEvent(document, 'click'); * var result = clicks.windowCount(3) * .map(win => win.skip(1)) // skip first of every 3 clicks * .mergeAll(); // flatten the Observable-of-Observables * result.subscribe(x => console.log(x)); * * @example Ignore every 3rd click event, starting from the third one * var clicks = Rx.Observable.fromEvent(document, 'click'); * var result = clicks.windowCount(2, 3) * .mergeAll(); // flatten the Observable-of-Observables * result.subscribe(x => console.log(x)); * * @see {@link window} * @see {@link windowTime} * @see {@link windowToggle} * @see {@link windowWhen} * @see {@link bufferCount} * * @param {number} windowSize The maximum number of values emitted by each * window. * @param {number} [startWindowEvery] Interval at which to start a new window. * For example if `startWindowEvery` is `2`, then a new window will be started * on every other value from the source. A new window is started at the * beginning of the source by default. * @return {Observable>} An Observable of windows, which in turn * are Observable of values. * @method windowCount * @owner Observable */ export function windowCount(windowSize, startWindowEvery = 0) { return higherOrder(windowSize, startWindowEvery)(this); } //# sourceMappingURL=windowCount.js.map
