Method Detail

onStart

public void onStart()

requestMore

void requestMore(long n)

onCompleted

public void onCompleted()

Description copied from interface: Observer

The Observable will not call this method if it calls Observer.onError(java.lang.Throwable).

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 method, it will not thereafter call Observer.onNext(T) or Observer.onCompleted().

Parameters:

e - the exception encountered by the Observable

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.

Parameters:

t - the item emitted by the Observable

decrementRequested

private void decrementRequested()

drain

private void drain()
