Description

Interface Summary

ServerRequestInterface	An interface for a genereic message processor for SIP Request messages.
ServerResponseInterface	An interface for a genereic message processor for SIP Response messages.
SIPTransactionEventListener	Interface implemented by classes that want to be notified of asynchronous transacion events.
StackMessageFactory	An interface for generating new requests and responses.

Class Summary

DefaultRouter	This is the default router.
HopImpl	Routing algorithms return a list of hops to which the request is routed.
MessageChannel	Message channel abstraction for the SIP stack.
MessageProcessor	This is the Stack abstraction for the active object that waits for messages to appear on the wire and processes these messages by calling the MessageFactory interface to create a ServerRequest or ServerResponse object.
ServerLog	Log file wrapper class.
SIPClientTransaction	Represents a client transaction.
SIPDialog	Tracks dialogs.
SIPServerTransaction	Represents a server transaction.
SIPStackTimerTask	A subclass of TimerTask which runs TimerTask code within a try/catch block to avoid killing the SIPTransactionStack timer thread.
SIPTransaction	Abstract class to support both client and server transactions.
SIPTransactionErrorEvent	An event that indicates that a transaction has encountered an error.
SIPTransactionStack	This is the sip stack.
TCPMessageChannel	This is a stack abstraction for TCP connections.
TCPMessageProcessor	Sit in a loop waiting for incoming tcp connections and start a new thread to handle each new connection.
TLSMessageChannel	This is sipStack for TLS connections.
TLSMessageProcessor	Sit in a loop waiting for incoming tls connections and start a new thread to handle each new connection.
UDPMessageChannel	This is the UDP Message handler that gets created when a UDP message needs to be processed.
UDPMessageProcessor	Sit in a loop and handle incoming udp datagram messages.

Package gov.nist.javax.sip.stack Description

This package implements the main protocol abstractions that are defined by the SIP RFC 3261. These include the following main ones:

• SIPServerTransaction -- an implementation of the Server Transaction State Machine (Chapter 17 of RFC 3261).
• SIPClientTransaction -- an implementation of the Client Transction State Machine (Chapter 17 of RFC 3261).
• SIPDialog -- an implementation of the SIP Dialog ( Chapter 11 of RFC 3261 ).

SIPTransactionStack is the container that holds references to these protocol objects.
