Class SipApplicationDispatcherImpl

java.lang.Object
  org.mobicents.servlet.sip.core.SipApplicationDispatcherImpl

All Implemented Interfaces:

java.util.EventListener, javax.management.MBeanRegistration, javax.sip.SipListener, SipApplicationDispatcher

public class SipApplicationDispatcherImpl
extends java.lang.Object
implements SipApplicationDispatcher, javax.management.MBeanRegistration

Implementation of the SipApplicationDispatcher interface. Central point getting the sip messages from the different stacks for a Tomcat Service(Engine), translating jain sip SIP messages to sip servlets SIP messages, creating a MessageRouter responsible for choosing which Dispatcher will be used for routing the message and dispatches the messages.
