示例1: flush
export function echo<T>(event: Event<T>, nextTick = false, buffer: T[] = []): { clear: () => void; event: Event<T> } {
buffer = buffer.slice();
event(e => {
buffer.push(e);
emitter.fire(e);
});
const flush = (listener: (e: T) => any, thisArgs?: any) => buffer.forEach(e => listener.call(thisArgs, e));
const clear = () => buffer = [];
const emitter = new Emitter<T>({
onListenerDidAdd(emitter, listener: (e: T) => any, thisArgs?: any) {
if (nextTick) {
setTimeout(() => flush(listener, thisArgs));
} else {
flush(listener, thisArgs);
}
}
});
return {
event: emitter.event,
clear
};
}示例2: event
export function debounceEvent<I, O>(event: Event<I>, merger: (last: O, event: I) => O, delay: number = 100, leading = false): { clear: () => void; event: Event<O> } {
let subscription: IDisposable;
let output: O = undefined;

let numDebouncedCalls = 0;
const clear = () => output = undefined;
const emitter = new Emitter<O>({

numDebouncedCalls++;
output = merger(output, cur);
if (leading && !handle) {
