示例1: sampleObservable
export function sampleObservable(obs: Observable<any>, scheduler?: any) {
return obs.pipe(
sampleTime(100, scheduler),
share(),
startWith('')
);
}示例2: it
it('should completes if source does not emits', () => {
const e1 = cold('|');
const e1subs = '(^!)';
const expected = '|';
expectObservable(e1.pipe(sampleTime(60, rxTestScheduler))).toBe(expected);
expectSubscriptions(e1.subscriptions).toBe(e1subs);
});示例3: asDiagram
asDiagram('sampleTime(70)')('should get samples on a delay', () => {
const e1 = hot('a---b-c---------d--e---f-g-h--|');
const e1subs = '^ !';
const expected = '-------c-------------e------h-|';
// timer -------!------!------!------!--
expectObservable(e1.pipe(sampleTime(70, rxTestScheduler))).toBe(expected);
expectSubscriptions(e1.subscriptions).toBe(e1subs);
});示例4: _updateUpdateRateObservable
