Package org.cometd.bayeux.server

Interface ServerSession.MaxQueueListener

All Superinterfaces:
Bayeux.BayeuxListener, EventListener, ServerSession.ServerSessionListener
Enclosing interface:
ServerSession
public static interface ServerSession.MaxQueueListener
extends ServerSession.ServerSessionListener

Listeners objects that implement this interface will be notified when the session queue is full.

This is a restricted listener interface because implementers are invoked while holding the session lock and therefore are restricted in the type of operations they may perform; in particular, publishing a message to another session may end up in a deadlock.
