Description

Interface Summary
Address: Abstract address.
ChannelFactory: Deprecated. Might get removed in 3.0.
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.
PhysicalAddress: Represents a physical (as opposed to logical) address
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
BlockEvent: Trivial object that represents a block event.
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.
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: Deprecated. Might get removed in 3.0.
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.
StateTransferException: `StateTransferException` is thrown to indicate failure of state transfer between cluster members.
SuspectedException: Thrown if a message is sent to a suspected member.
