Package org.jboss.cache.lock

Interface Summary
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 Interface for a lock for nodes.
 

Class Summary
IdentityLock Lock object which grants and releases locks, and associates locks with owners.
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  
NodeBasedLockManager  
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.
SimpleLock Simple lock that does not differentiate read and write lock.
SimpleReadWriteLock  
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
IsolationLevel Various transaction isolation levels as an enumerated class.
LockType An enumeration to define different types of locks.
 

Exception Summary
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
