Hi all,
I am trying to use the ITaskLock classes, but I have a problem with the lock valid time setting. This is the documentation I was able to obtain.
/**
- Acquires distributed lock for the given task. Lock is identified by source. Lock will be valid specified time.
- If there is an active lock on the given task it will wait specified time
- @param sourceURI source URI for the lock
-
@param taskURI task to be locks
* @param validTime time in millis the lock will be valid - @param waitTime waiting time to acquire a lock (0 - immediately exit if lock can not be obtained)
- @return acquired lock instance or null if unable to acquire a lock
-
@throws PortalException
*/
ITaskLock acquireLock(IURI sourceURI, IURI taskURI, long validTime, long waitTime) throws PortalException;
I create the lock using validTime = 120000 (2 minutes).
ITaskLock lock = TaskHelper.getTaskLockingService().acquireLock(context.getUserID(), lockUri, 120000, 0);
At this point I would expect that after two minutes, when I try to get the lock I get nothing
ITaskLock lock = TaskHelper.getTaskLockingService().getLock(lockUri);
However, the lock object still exists and is still valid:
lock.isExpired(); => returns false.
So my question is :
Does anyone know for sure how the lock actually behaves? And how to have a lock automatically released after some time (validTime).
Thanx
