Package org.jboss.cache.lock

Interface Summary

Interface	Description
LockManager	An interface to deal with all aspects of acquiring and releasing locks for nodes in the cache.
LockStrategy	Interface to specify lock strategy, e.g., for different isolation levels.
NodeLock	Deprecated will be removed when we drop support for Pessimistic Locking and Optimistic Locking

Class Summary

Class	Description
AbstractLockManager	Common lock manager functionality
FqnLockManager	An abstract lock manager that deals with Fqns rather than nodes.
IdentityLock	Deprecated will be removed when we drop support for Pessimistic Locking and Optimistic Locking
LockMap	Provide lock ownership mapping.
LockStrategyFactory	Factory to create LockStragtegy instance.
LockStrategyNone	Transaction isolation level of None.
LockStrategyReadCommitted	Transaction isolation level of READ_COMMITTED.
LockStrategyReadUncommitted	Transaction isolation level of READ-UNCOMMITTED.
LockStrategyRepeatableRead	Transaction isolation level of Repeatable_Read.
LockStrategySerializable	Lock strategy of Serializable that prevents dirty read, non-repeatable read, and phantom read.
LockUtil
MVCCLockManager	This lock manager acquires and releases locks based on the Fqn passed in and not on the node itself.
NodeBasedLockManager	Deprecated since this is specific to legacy locking schemes
NonBlockingWriterLock	NonBlockingWriterLock is a read/write lock (with upgrade) that has non-blocking write lock acquisition on existing read lock(s).
PessimisticNodeBasedLockManager	Deprecated will be removed with pessimistic locking
ReadWriteLockWithUpgrade	This class is similar to PreferredWriterReadWriteLock except that the read lock is upgradable to write lock.
SemaphoreLock	Implements most of the methods of Lock using the Semaphore implementation.
StripedLock	A simple implementation of lock striping, using Fqns as the keys to lock on, primarily used to help make CacheLoader implemtations thread safe.
ThreadLocalMap<K,V>	Map which reduces concurrency and potential memory leaks for non-static ThreadLocals.

Enum Summary

Enum	Description
IsolationLevel	Various transaction isolation levels as an enumerated class.
LockType	An enumeration to define different types of locks.

Exception Summary

Exception	Description
DeadlockException	Used when a lock acquisition would cause a deadlock.
LockingException	Used for all locking-related exceptions, e.g.
OwnerNotExistedException
TimeoutException	Thrown when a timeout occurred.
UpgradeException	Used when a read-lock cannot be upgraded to a write-lock
