Interface VirtualLockTable
public interface VirtualLockTable
This class acts as a conduit of information between the lock manager and
the outside world. Once a virtual lock table is initialized, it contains
a snap shot of all the locks currently held in the lock manager. A VTI can
then be written to query the content of the lock table.
Each lock held by the lock manager is represented by a Hashtable. The key
to each Hashtable entry is a lock attribute that is of interest to the
outside world, such as transaction id, type, mode, etc.
