          Description

Interface Summary
Command The Command patttern (see Gamma et al.).
SchedulerListener Provides callback for use with a Scheduler.
Streamable Implementations of Streamable can add their state directly to the output stream, enabling them to bypass costly serialization
ThreadLocalListener Provides callback for use with a ReusableThread.
TimeScheduler.CancellableTask  
TimeScheduler.Task The interface that submitted tasks must implement
 

Class Summary
AckCollector  
BoundedList A bounded subclass of List, oldest elements are removed once max capacity is exceeded
Buffer Buffer with an offset and length.
CondVar Class that checks on a condition and - if condition doesn't match the expected result - waits until the result matches the expected result, or a timeout occurs.
ContextObjectInputStream ObjectInputStream which sets a contact classloader for reading bytes into objects.
ExposedBufferedInputStream  
ExposedBufferedOutputStream  
ExposedByteArrayInputStream  
ExposedByteArrayOutputStream Extends ByteArrayOutputStream, but exposes the internal buffer.
ExposedDataOutputStream  
GetNetworkInterfaces Lists all network interfaces on a system
HashUtils Helper class for performing some common hashing methods
ImmediateTask Task which is executed immediately and only one time
LinkedListQueue LinkedListQueue implementation based on java.util.Queue.
List Doubly-linked list.
MagicObjectInputStream Uses magic numbers for class descriptors
MagicObjectOutputStream Uses magic numbers for class descriptors
Marshaller Title: JGroups Communications Description: Contact me at mail@filip.net Copyright: Copyright (c) 2002 Company: www.filip.net
NullReadWriteLock  
NullSync  
Promise Allows a thread to submit an asynchronous request and to wait for the result.
Proxy Redirects incoming TCP connections to other hosts/ports.
Queue Elements are added at the tail and removed from the head.
Queue2 Elements are added at the tail and removed from the head.
Range  
ReusableThread Reusable thread class.
Rsp class that represents a response from a communication
RspList Contains responses from all members.
Scheduler Implementation of a priority scheduler.
Scheduler.Task  
Stack LIFO stack, with better performance than java.util.Stack (based on List).
ThreadPool Maintains a set of ReusableThreads.
TimedWriter Waits until the buffer has been written to the output stream, or until timeout msecs have elapsed, whichever comes first.
TimeScheduler Fixed-delay & fixed-rate single thread scheduler

The scheduler supports varying scheduling intervals by asking the task every time for its next preferred scheduling interval.

UnmodifiableVector Vector which cannot be modified
Util Collection of various utility routines that can not be assigned to other classes.
 

Exception Summary
QueueClosedException
