Method Details

onNext

public void onNext(T outer)

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).

Parameters:

outer - the item emitted by the Observable

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().

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).

setProducer

public void setProducer(Producer p)

Description copied from class: Subscriber

If other subscriber is set (by calling constructor Subscriber(Subscriber) or Subscriber(Subscriber, boolean)) then this method calls setProducer on the other subscriber. If the other subscriber is not set and no requests have been made to this subscriber then p.request(Long.MAX_VALUE) is called. If the other subscriber is not set and some requests have been made to this subscriber then p.request(n) is called where n is the accumulated requests to this subscriber.

Overrides:

setProducer in class Subscriber<T>

Parameters:

p - producer to be used by this subscriber or the other subscriber (or recursively its other subscriber) to make requests from
