Uses of ReadLockManager in org.eclipse.persistence.internal.helper

Methods in org.eclipse.persistence.internal.helper that return ReadLockManager

Modifier and Type	Method	Description
ReadLockManager	ReadLockManager.clone()	Create a new instance ReadLockManager that is in all regards equal to the current instance.
protected static ReadLockManager	ConcurrencyManager.getReadLockManager(Thread thread)	The method is not synchronized because for now we assume that each thread will ask for its own lock manager.
protected static ReadLockManager	ConcurrencyManager.getReadLockManagerEnsureResultIsNotNull(Thread thread)	Same as ConcurrencyManager.getReadLockManager(Thread) but in this case a not null result is ensured

Methods in org.eclipse.persistence.internal.helper that return types with arguments of type ReadLockManager

Modifier and Type	Method	Description
Map<Thread,ReadLockManager>	ConcurrencyUtil.cloneReadLockManagerMap(Map<Thread,ReadLockManager> readLockManagersOriginal)	To facilitate algorithms that want to dump a snapshot of the current state of the concurrency manager or to start a hunt for dead locks this api faciliates the boostraping logic of such algorithms by giving the algorithm a stable clone of the map of read locks that we know will not change throughout the time the algorithm is running.
protected static Map<Thread,ReadLockManager>	ConcurrencyManager.getReadLockManagers()	Return the deferred lock manager hashtable (thread - DeferredLockManager).

Methods in org.eclipse.persistence.internal.helper with parameters of type ReadLockManager

Modifier and Type	Method	Description
protected String	ConcurrencyUtil.createInformationAboutAllResourcesAcquiredAndDeferredByThread(ReadLockManager readLockManager, DeferredLockManager lockManager, Set<ConcurrencyManager> waitingOnAcquireCacheKeys, ConcurrencyManager waitingOnAcquireReadCacheKey, boolean threadWaitingToReleaseDeferredLocks, Thread thread, int currentThreadNumber, int totalNumberOfThreads, Set<Object> writeManagerThreadPrimaryKeysWithChangesToBeMerged, String waitingToReleaseDeferredLocksJustification)	Build a string that tries to describe in as much detail as possible the resources associated to the current thread.
protected String	ConcurrencyUtil.currentThreadIsStuckForSomeTimeProduceTinyLogMessage(long elapsedTime, ConcurrencyManager concurrencyManager, DeferredLockManager lockManager, ReadLockManager readLockManager)	We have a thread that is not evolving for quite some while.
void	ConcurrencyUtil.determineIfReleaseDeferredLockAppearsToBeDeadLocked(ConcurrencyManager concurrencyManager, long whileStartTimeMillis, DeferredLockManager lockManager, ReadLockManager readLockManager, boolean callerIsWillingToAllowInterruptedExceptionToBeFiredUpIfNecessary)	Throw an interrupted exception if appears that eclipse link code is taking too long to release a deferred lock.

Method parameters in org.eclipse.persistence.internal.helper with type arguments of type ReadLockManager
