Class Summary

AckMcastReceiverWindow	Keeps track of messages received from various senders.
AckMcastSenderWindow	Keeps track of ACKs from receivers for each message.
AckReceiverWindow	Stores received messages according to their sequence numbers.
AckSenderWindow	ACK-based sliding window for a sender.
BlockEvent
Channel	A channel represents a group communication endpoint (like BSD datagram sockets).
DistributedHashtable	Provides the abstraction of a java.util.Hashtable that is replicated at several locations.
EnsChannel	EnsChannel is an implementation of Channel based on Ensemble.
EnsChannelFactory
Event	Used for inter-stack and intra-stack communication.
GetStateEvent
GroupRequest	Sends a message to all members of the group and waits for all responses (or timeout).
Header	Container for header data which is added to the front of a Message by a protocol layer when traveling down the stack.
IbusChannel	Implementation of a channel using iBus.
IbusChannelFactory
JChannel	JChannel is a pure Java implementation of Channel.
JChannelFactory
List	Doubly-linked list.
Message
MessageDispatcher	Used on top of channel to implement group requests.
MethodCall
MethodLookupClos
MethodLookupJava
NakReceiverWindow	Keeps track of messages according to their sequence numbers.
Profiler	Allows to time execution of 'named' statements, counts number of times called and total execution time.
Profiler.Entry
PullPushAdapter	Allows a client of Channel to be notified when messages have been received instead of having to actively poll the channel for new messages.
Queue	Elements are added at the tail and removed from the head.
RequestCorrelator	Framework to send requests and receive matching responses (matching on request ID).
ReusableThread	Reusable thread class.
RpcDispatcher	Dispatches and receives remote group method calls.
Rsp
RspList	Contains responses from all members.
Scheduler	Implementation of a priority scheduler.
SetStateEvent	Encapsulates a state returned by Channel.Receive(), as requested by Channel.GetState(s) previously.
SortedList	Keeps elements in sorted order (ascending or decending).
Stack	LIFO stack, with better performance than java.util.Stack (based on Vector).
StateTransferInfo	Contains parameters for state transfer.
SuspectEvent
ThreadPool	Maintains a set of ReusableThreads.
Util	Collection of various utility routines that can not be assigned to other classes.
Version
View
ViewId	ViewIds are used for ordering views (each view has a ViewId and a list of members).
