Package org.apache.commons.transaction.locking Description

Locking:

Central package for locking related stuff. It contains interfaces and implementations to handle your locks in a transactional way. That means you divide your work in blocks and free all locks accumulated in that block at its very end. A common, shared timeout protects all locking requests.

The central interface is the one of the lock manager. It's recommended implementation is the read/write lock manager that features read/write locks and efficient deadlock detection.

If you have hierarchical resources to lock you can use the hierarchical lock manager interface with its default implementation.

If you need a custom implementation of a lock mamanger it is recommended to base your work on the on an abstract base.
