Method Detail

onStart

public void onStart()

Description copied from class: Subscriber

This method is invoked when the Subscriber and Observable have been connected but the Observable has not yet begun to emit items or send notifications to the Subscriber. Override this method to add any useful initialization to your subscription, for instance to initiate backpressure.

Overrides:

onStart in class Subscriber<T>

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

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().

Specified by:

onError in interface Observer<T>

Parameters:

e - the exception encountered 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>

call

public void call()

Specified by:

call in interface Action0

emitIfNonEmpty

private void emitIfNonEmpty()
