     Obtain lock on obj for specified owner.
 voidunlock(Object obj, Object owner)
     Release lock on obj owned by specified owner.
 voidunlock(Object obj, Object owner, boolean releaseMultiLocked)
     Release lock on obj owned by specified owner.



Method Detail
lock
void lock(Object obj, Object owner, int timeout) throws LockNotGrantedException, ClassCastException, ChannelException(Code)
Obtain lock on obj for specified owner. Implementation should try to obtain lock few times within the specified timeout.
Parameters:
  obj - obj to lock, usually not full object but object's ID.
Parameters:
  owner - object identifying entity that will own the lock.
Parameters:
  timeout - maximum time that we grant to obtain a lock.
throws:
  LockNotGrantedException - if lock is not granted withinspecified period.
throws:
  ClassCastException - if obj and/orowner is not of type that implementation expects to get(for example, when distributed lock manager obtains non-serializableobj or owner).
throws:
  ChannelException - if something bad happened to communicationchannel.



unlock
void unlock(Object obj, Object owner) throws LockNotReleasedException, ClassCastException, ChannelException(Code)
Release lock on obj owned by specified owner. since 2.2.9 this method is only a wrapper for unlock(Object lockId, Object owner, boolean releaseMultiLocked). Use that with releaseMultiLocked set to true if you want to be able to release multiple locked locks (for example after a merge)
Parameters:
  obj - obj to lock, usually not full object but object's ID.
Parameters:
  owner - object identifying entity that will own the lock.
throws:
  LockOwnerMismatchException - if lock is owned by another object.
throws:
  ClassCastException - if obj and/orowner is not of type that implementation expects to get(for example, when distributed lock manager obtains non-serializableobj or owner).
throws:
  ChannelException - if something bad happened to communicationchannel.



unlock
void unlock(Object obj, Object owner, boolean releaseMultiLocked) throws LockNotReleasedException, ClassCastException, ChannelException, LockMultiLockedException(Code)
Release lock on obj owned by specified owner.
Parameters:
  obj - obj to lock, usually not full object but object's ID.
Parameters:
  owner - object identifying entity that will own the lock.
Parameters:
  releaseMultiLocked - force unlocking of the lock if the locallockManager owns the lock even if another lockManager owns the same lock
throws:
  LockOwnerMismatchException - if lock is owned by another object.
throws:
  ClassCastException - if obj and/orowner is not of type that implementation expects to get(for example, when distributed lock manager obtains non-serializableobj or owner).
throws:
  ChannelException - if something bad happened to communicationchannel.
throws:
  LockMultiLockedException - if the lock was unlocked, but anothernode already held the lock
