Interface MessageListener

All Superinterfaces:

java.util.EventListener

All Known Subinterfaces:

TraceMessageListener

public interface MessageListener
extends java.util.EventListener

A low-level listener that is inserted into the Transaction and Transport layers of the SIP stack. Implementations of this interface are notified when a new message is received by the container, or a message is about to be sent. Note that message retransmissions are not supressed, so an implementation of this interface must be prepared to handle potentially large volumes of messages.
