Interface Summary

Address	Abstract address.
ChannelFactory	A channel factory that removes hardwiring of calls to create JGroups channels.
ChannelListener	Allows a listener to be notified when important channel events occur.
ExtendedMembershipListener
ExtendedMessageListener	ExtendedMessageListener has additional callbacks for: partial state transfer - http://jira.jboss.com/jira/browse/JGRP-118 streaming state transfer - http://jira.jboss.com/jira/browse/JGRP-89
ExtendedReceiver	Extends Receiver, plus the partial state transfer methods.
MembershipListener	Allows a listener to be notified when group membership changes.
MessageListener	Allows a listener to be notified when a message arrives.
Receiver	Defines the callbacks that are invoked when messages, views etc are received on a channel
Transport	Defines a very small subset of the functionality of a channel, essentially only the methods for sending and receiving messages.
UpHandler	Provides a way of taking over a channel's tasks.

Class Summary

Channel	A channel represents a group communication endpoint (like BSD datagram sockets).
ChannelListenerAdapter	Class which implements ChannelListener
Event	Used for inter-stack and intra-stack communication.
ExitEvent	Trivial object that represents an exit event.
ExtendedReceiverAdapter
GetStateEvent	Represents a GetState event.
Global	Globals used by JGroups packages.
Header	Abstract base class for all headers to be added to a Message.
JChannel	JChannel is a pure Java implementation of Channel.
JChannelFactory	JChannelFactory creates pure Java implementations of the Channel interface.
Membership	Class to keep track of Addresses.
MergeView	A view that is sent as a result of a merge.
Message	A Message encapsulates data sent to members of a group.
ReceiverAdapter
SetStateEvent	Encapsulates a state returned by Channel.receive(), as requested by Channel.getState(s) previously.
StreamingGetStateEvent	Represents an event returned by channel.receive(), as a result of another channel instance requesting a state from this channel.
StreamingSetStateEvent	Represents an event returned by channel.receive(), as requested by channel.getState() previously.
SuspectEvent	Represents a suspect event.
UnblockEvent	Trivial object that represents a block event.
Version	We're using the scheme described at http://www.jboss.com/index.html?module=bb&op=viewtopic&t=77231 for major, minor and micro version numbers.
View	A view is a local representation of the current membership of a group.
ViewId	ViewIds are used for ordering views (each view has a ViewId and a list of members).

Exception Summary

ChannelClosedException	Thrown if an operation is attemped on a closed channel.
ChannelException	This class represents the super class for all exception types thrown by JGroups.
ChannelNotConnectedException	Thrown if an operation is attemped on an unconnected channel.
