Constructor Details

ObserveOnSubscriber

public ObserveOnSubscriber(Scheduler scheduler,
 Subscriber<? super T> child,
 boolean delayError,
 int bufferSize)

Method Details

init

void init()

onNext

public void onNext(T t)

Description copied from interface: Observer

Provides the Observer with a new item to observe.

The Observable may call this method 0 or more times.

The Observable will not call this method again after it calls either Observer.onCompleted() or Observer.onError(java.lang.Throwable).

Specified by:

onNext in interface Observer<T>

Parameters:

t - the item emitted by the Observable

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 method if it calls Observer.onError(java.lang.Throwable).

Specified by:

onCompleted in interface Observer<T>

onError

public void onError(Throwable e)

Description copied from interface: Observer

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

If the Observable calls this method, it will not thereafter call Observer.onNext(T) or Observer.onCompleted().

Specified by:

onError in interface Observer<T>

Parameters:

e - the exception encountered by the Observable

schedule

protected void schedule()

call

public void call()

Specified by:

call in interface Action0

checkTerminated

boolean checkTerminated(boolean done,
 boolean isEmpty,
 Subscriber<? super T> a,
 Queue<Object> q)
