Classes in org.jgroups.util used by org.jgroups

Buffer
Buffer with an offset and length.

Headers
Open addressing based implementation of a hashmap (not supporting the Map interface though) for message headers.

Streamable
Implementations of Streamable can add their state directly to the output stream, enabling them to bypass costly serialization

PortsManager
Maintains a list of ports used on this host, associated with time stamps.

Promise
Allows a thread to submit an asynchronous request and to wait for the result.

RspList
Contains responses from all members.

Scheduler
Implementation of a priority scheduler.

AgeOutCache
Cache which removes its elements after a certain time

AgeOutCache.Handler

PortsManager
Maintains a list of ports used on this host, associated with time stamps.

Promise
Allows a thread to submit an asynchronous request and to wait for the result.

Streamable

ThreadFactory

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.

BoundedList
A bounded subclass of LinkedList, oldest elements are removed once max capacity is exceeded.

Digest
A message digest, which is used by the PBCAST layer for gossiping (also used by NAKACK for keeping track of current seqnos for all members).

ThreadFactory

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.

Tuple
Holds 2 values, useful when we have a map with a key, but more than 1 value and we don't want to create a separate holder object for the values, and don't want to pass the values as a list or array.

AgeOutCache.Handler

Buffer

ContextObjectInputStream
ObjectInputStream which sets a contact classloader for reading bytes into objects.

DefaultThreadFactory
Thread factory mainly responsible for naming of threads.

Digest
A message digest, which is used by the PBCAST layer for gossiping (also used by NAKACK for keeping track of current seqnos for all members).

Digest.Entry
Class keeping track of the lowest and highest sequence numbers delivered, and the highest sequence numbers received, per member.

Provides callback for use with a Scheduler.

Streamable

ThreadDecorator
An object that can alter the state of a thread when it receives a callback from a ThreadManager notifying it that the thread has been created or released from use.

ThreadFactory

ThreadManager
An object that manages threads and provides callbacks to a ThreadDecorator to allow it to alter their state.

TimeScheduler.Task
The interface that submitted tasks must implement
