    • _connect

      protected Future<?> _connect(boolean forceReconnect)
      Description copied from class: Computer
      Allows implementing-classes to provide an implementation for the connect method.

      If already connected or if this computer doesn't support proactive launching, no-op. This method may return immediately while the launch operation happens asynchronously.

      Specified by:
      _connect in class Computer
      Parameters:
      forceReconnect - If true and a connect activity is already in progress, it will be cancelled and the new one will be started. If false, and a connect activity is already in progress, this method will do nothing and just return the pending connection operation.
      Returns:
      A Future representing pending completion of the task. The 'completion' includes both a successful completion and a non-successful completion (such distinction typically doesn't make much sense because as soon as Computer is connected it can be disconnected by some other threads.)
