extends Observable<T>
implements Observer<T>

A solution to the "time gap" problem that occurs with `groupBy` and `pivot` => https://github.com/Netflix/RxJava/issues/844 This currently has temporary unbounded buffers. It needs to become bounded and then do one of two things: 1) blow up and make the user do something about it 2) work with the backpressure solution ... still to be implemented (such as co-routines) Generally the buffer should be very short lived (milliseconds) and then stops being involved. It can become a memory leak though if a GroupedObservable backed by this class is emitted but never subscribed to (such as filtered out). In that case, either a time-bomb to throw away the buffer, or just blowing up and making the user do something about it is needed. For example, to filter out GroupedObservables, perhaps they need a silent `subscribe()` on them to just blackhole the data. This is an initial start at solving this problem and solves the immediate problem of `groupBy` and `pivot` and trades off the possibility of memory leak for deterministic functionality.

Method Detail

create

public static <T> BufferUntilSubscriber<T> create()

onCompleted

public void onCompleted()

Description copied from interface: Observer

Notifies the Observer that the Observable has finished sending push-based notifications.

The Observable will not call this closure if it calls onError.

Specified by:

onCompleted in interface Observer<T>

onError

public void onError(java.lang.Throwable e)

Description copied from interface: Observer

Notifies the Observer that the Observable has experienced an error condition.

If the Observable calls this closure, it will not thereafter call onNext or onCompleted.

Specified by:

onError in interface Observer<T>

onNext

public void onNext(T t)

Description copied from interface: Observer

Provides the Observer with new data.

The Observable calls this closure 1 or more times, unless it calls onError in which case this closure may never be called.

The Observable will not call this closure again after it calls either onCompleted or onError.

Specified by:

onNext in interface Observer<T>
