        This information describes the DbLockNotGrantedException class and how 
        it is used by the various Berkeley DB classes.
    
        A DbLockNotGrantedException is thrown when
        lock or transaction timeouts have been configured, a database operation has timed out, and the
        DB_TIME_NOTGRANTED 
        configuration flag has been specified.
    
        Additionally DbLockNotGrantedException is thrown when a Berkeley DB
        Concurrent Data Store database environment configured for lock timeouts was unable to grant
        a lock in the allowed time.
    
        Finally, DbLockNotGrantedException is thrown when a lock requested using the
        DbEnv::lock_get()
        or
        DbEnv::lock_vec()
        methods, where the DB_LOCK_NOWAIT
        flag or lock timers were configured, could not be granted before the wait-time expired.
    
        The DbException errno value is set to
        DB_LOCK_NOTGRANTED.
    
The following getter methods are available on this class:
                get_op()
            
                Returns DB_LOCK_GET when DbEnv::lock_get()
                was called, and returns the op for the failed
                DB_LOCKREQ when DbEnv::lock_vec()
                was called. If this exception is raised due to a database
                operation, DB_LOCK_GET is returned.
            
                get_mode()
            
                Returns the mode parameter when 
                DbEnv::lock_get() was called, and returns the
                mode for the failed DB_LOCKREQ
                when DbEnv::lock_vec() was called.
                If this exception is raised due to a database operation, 
                DB_LOCK_NG is returned.
            
                get_obj()
            
                Returns the object parameter when 
                DbEnv::lock_get() was called, and returns the
                object for the failed DB_LOCKREQ
                when DbEnv::lock_vec() was called.
                The Dbt pointer may or may not refer valid
                memory, depending on whether the Dbt
                used in the call to the failed DbEnv::lock_get()
                or DbEnv::lock_vec() method is still in
                scope and has not been deleted.
            
                get_lock()
            
                Returns NULL when DbEnv::lock_get() was called, 
                and returns the lock in the failed DB_LOCKREQ
                when DbEnv::lock_vec() was called.
                If this exception is raised due to a database operation, NULL is returned.
            
                get_index()
            
                Returns -1 when DbEnv::lock_get() was called, 
                and returns the index of the failed DB_LOCKREQ
                when DbEnv::lock_vec() was called.
                If this exception is raised due to a database operation, 
                0 is returned.
