Description

Interface Summary

ConcurrentMap	A highly concurrent map.
Condition	Condition factors out the Object monitor methods(wait, notify and notifyAll) into distinct objects to give the effect of having multiple wait-sets per object, by combining them with the use of arbitrary Lock implementations.
Lock	Lock implementations provide more extensive locking operations than can be obtained using synchronized methods and statements.
NanoTimer	Interface to specify custom implementation of precise timer.
Queue	A collection designed for holding elements prior to processing.
WaitQueue.QueuedSync

Class Summary

AbstractConcurrentEventManager	Base event manager that handles adding/removing listeners and firing events.
ConcurrentHashMap	This class implements a HashMap which has limited synchronization.
ConcurrentHashMap.Entry
ConcurrentHashSet	A concurrent set.
ConcurrentLinkedQueue	An unbounded thread-safe queue based on linked nodes.
ConcurrentReferenceHashMap	This class implements a HashMap which has limited synchronization and reference keys or values(but not both).
ConcurrentReferenceHashSet	A concurrent set whose values may be stored as weak or soft references.
CopyOnWriteArrayList
CopyOnWriteArraySet	A Set that uses an internal CopyOnWriteArrayList for all of its operations.
ReentrantLock	A reentrant mutual exclusion Lock with the same basic behavior and semantics as the implicit monitor lock accessed using synchronized methods and statements, but with extended capabilities.
TimeUnit	A TimeUnit represents time durations at a given unit of granularity and provides utility methods to convert across units, and to perform timing and delay operations in these units.
Utils	This class groups together the functionality of java.util.concurrent that cannot be fully and reliably implemented in backport, but for which some form of emulation is possible.
WaitQueue	Base class for internal queue classes for semaphores, etc.
WaitQueue.WaitNode
