rx.subjects
Class AsyncSubject<T>

java.lang.Object
  rx.Observable<R>
      rx.subjects.Subject<T,T>
          rx.subjects.AsyncSubject<T>

Type Parameters:

T -

All Implemented Interfaces:

Observer<T>

public class AsyncSubject<T>
extends Subject<T,T>

Subject that publishes only the last event to each Observer that has subscribed when the sequence completes.

Example usage:

 / observer will receive no onNext events because the subject.onCompleted() isn't called.
  AsyncSubject<Object> subject = AsyncSubject.create();
  subject.subscribe(observer);
  subject.onNext("one");
  subject.onNext("two");
  subject.onNext("three");

  // observer will receive "three" as the only onNext event.
  AsyncSubject<Object> subject = AsyncSubject.create();
  subject.subscribe(observer);
  subject.onNext("one");
  subject.onNext("two");
  subject.onNext("three");
  subject.onCompleted();

                       rx.subjects.AsyncSubject.AsyncSubjectState<T> state)

Method Detail

create

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

Create a new AsyncSubject

Returns:

a new AsyncSubject

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.

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.

onNext

public void onNext(T v)

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.
