Class SipApplicationSessionImpl

java.lang.Object
  org.mobicents.servlet.sip.core.session.SipApplicationSessionImpl

All Implemented Interfaces:

SipApplicationSession, MobicentsSipApplicationSession

Direct Known Subclasses:

ClusteredSipApplicationSession

public class SipApplicationSessionImpl
extends java.lang.Object
implements MobicentsSipApplicationSession

Implementation of the SipApplicationSession interface. An instance of this sip application session can only be retrieved through the Session Manager (extended class from Tomcat's manager classes implementing the Manager interface) to constrain the creation of sip application session and to make sure that all sessions created can be retrieved only through the session manager

As a SipApplicationSession represents a call (that can contain multiple call legs, in the B2BUA case by example), the call id and the app name are used as a unique key for a given SipApplicationSession instance.
