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.
