Examples of IEntityLock

org.jasig.portal.concurrency.IEntityLock
Defines a lock associated with an owner and a portal entity that guarantees some degree of exclusive access to the entity, depending on lockType and expirationTime. See IEntityLockService for the rules governing lock assignment and a code example. @author Dan Ellentuck @version $Revision: 19776 $ @see org.jasig.portal.concurrency.IEntityLockService
