Method Detail

acquire

ExtendedLockPromise acquire(Object key,
                            Object lockOwner,
                            long time,
                            TimeUnit timeUnit)

Parameters:

key - the key to lock.

Returns:

the lock for a specific object to be acquired. If the lock does not exists, it is created.

getLock

InfinispanLock getLock(Object key)

Parameters:

key - the key to lock.

Returns:

the lock for a specific object. If the lock does not exists, it return null.

release

void release(Object key,
             Object lockOwner)

getNumLocksHeld

int getNumLocksHeld()

Returns:

number of locks held

isLocked

boolean isLocked(Object key)

Parameters:

key - the key to test.

Returns:

true if the key is locked, false otherwise.

size

int size()

Returns:

the size of the shared lock pool

deadlockCheck

void deadlockCheck(DeadlockChecker deadlockChecker)

It forces a deadlock checks in all existing locks.
