Method Detail

addListener

void addListener(PublisherCallbackChannel.Listener listener)

Adds a PublisherCallbackChannel.Listener.

Parameters:

listener - The Listener.

expire

java.util.Collection<PendingConfirm> expire(PublisherCallbackChannel.Listener listener,
                                            long cutoffTime)
