Registeragent class

In Transactionclient Fail/success callback, the Registeragentlistener register Fail/sucess interface is called

 Public classRegisteragentImplementsTransactionclientlistener, Subscriberdialoglistener {
　　Registeragentlistener Listener;
 Publicregisteragent (... Registeragentlistener Listener, ...) {}     Public voidOntranssuccessresponse (transactionclient ransaction, Message resp) {listener.onuaregistrationsuccess ( This, target, contact, result); }     Public voidontransfailureresponse (transactionclient, Message resp) { listener.onuaregistrationfailure (  This , Target, contact, result); }     Public voidontranstimeout (transactionclient transaction) {Listener.onuaregistrationfailure ( This, Target, Contac, "Timeout"); Listener.onuaregistrationsuccess ( This, Target, Contac, "Timeout"); }}

Transactionclient class/--->sipproviderlistener1. Extends Transaction

 Public Abstract class Implements Sipproviderlistener, TimerListener {    publicvoid  onreceivedmessage (sipprovider Provider, Message msg) {}}

2. Transactionclient class

In the callback of the transaction fail/success (actual Sipprovider callback), the Fail/sucess interface of the transactionclient is called

 Public classTransactionclientextendsTransaction {Transactionclientlistener transaction_listener;  Publictransactionclient (Sipprovider sip_provider, Message req, Transactionclientlistener listener) {Super(Sip_provider); Request=NewMessage (req); Init (Listener, Request.gettransactionid ()); //This.transaction_listener = listener;} //The actual Sipprovider callback
 Public voidOnreceivedmessage (Sipprovider provider, Message msg) {Transaction_listener.ontranssuccessresponse ( This, MSG); Transaction_listener.ontransfailureresponse ( This, MSG); } pulicvoidOnTimeOut (Timer to) {//Transaction_listener callback associated with the timeout    }}

So, what object is Sipproviderlistener triggered?
