    • lockDSS

      protected boolean lockDSS(boolean lock, int lockThreadToken)
      lockDSS is for synchronized access to DSS This function sets a static value to indicate access for a single thread for DSS. Generally, no waiting will be needed unless several threads are hammering DSS at the same time In version 6, there is only one thread per VM that can access DSS In version 7, there is one thread per DSS file. (This has not yet been implemented!)

      lock -
      lockThreadToken -
