Force flush to Observable.Buffer c#

Question

Is there any way to force a Observable.Buffer to flush before the end of buffered time?

In the example:

mSubscription = mFluxObservable.Buffer(new Time

Answer 1

...and basically the same principal using window:

var bufferPeriod = TimeSpan.FromSeconds(1.5);
var source = Observable.Interval(TimeSpan.FromMilliseconds(100)).Take(50);

//source.Buffer(bufferPeriod).Dump();

var bufferFlush = new Subject();//Or Subject
source.Window(
        ()=>Observable.Merge(Observable.Timer(bufferPeriod), bufferFlush))
    .Select(window=>window.ToList())
    .Dump();

//Simulate calling flush.
Observable.Interval(TimeSpan.FromMilliseconds(1350)).Take(2).Subscribe(bufferFlush);
