TGo4CommandRunnable Class Reference

Runnable responsible for command exchange between transport (socket) and buffer (queue) In receiver mode, commands are received from transport, checked if sync or not, the command receiver of system (client) commands is set to the clienttask, sync commands are executed directly, async commands are passed to the queue in not receiver mode, runnables waits for the queue and sends all commands from the queue over the transport.
