All Implemented Interfaces:

ReadWriteLock

Deprecated.

This class hasn't been in use since the introduction of MVCC which is now how concurrent access to RAM data structures is handled.

public class HGLock
extends Object
implements ReadWriteLock

An implementation of ReadWriteLock that will use the currently active database transaction if there is one (through BDBTxLock) or a default ReentrantReadWriteLock if there is no current transaction. The implementation is useful for runtime data structures that need protection from concurrent access and that may or may not participate in a database transaction.
