示例1: windowTime1
windowTime1() {
// emit immediately then every 1s
const source = timer(0, 1000);
const example = source.pipe(
// start new window every 3s
windowTime(3000),
tap(_ => console.log('NEW WINDOW!'))
);
const subscribeTwo = example
.pipe(
// window emits nested observable
mergeAll()
/*
output:
"NEW WINDOW!"
0
1
2
"NEW WINDOW!"
3
4
5
*/
)
.subscribe(val => console.log(val));
}示例2: if
export function windowTime<T>(this: Observable<T>,
windowTimeSpan: number): Observable<Observable<T>> {
let scheduler: SchedulerLike = asyncScheduler;
let windowCreationInterval: number = null;
let maxWindowSize: number = Number.POSITIVE_INFINITY;

return higherOrder(windowTimeSpan, windowCreationInterval, maxWindowSize, scheduler)(this) as Observable<Observable<T>>;
