sharedLock

sharedLock(lockTarget: Object);

The sharedLock method of the Object class attempts to acquire a shared lock on the object specified in the lockTarget parameter.

An object that is locked by a shared lock cannot be locked with an exclusive lock or updated by other processes, but it can be locked by another shared lock or a reserve lock.

For more details, see "Locking Objects", in Chapter 6 of the JADE Developer’s Reference.
