int TAO_Reactive_Flushing_Strategy::cancel_output ( TAO_Transport * transport ) [virtual]

Cancel all scheduled output for the transport argument.

Implements TAO_Flushing_Strategy.

Definition at line 23 of file Reactive_Flushing_Strategy.cpp.

{
  return transport->cancel_output_i ();
}

int TAO_Reactive_Flushing_Strategy::flush_message	(	TAO_Transport *	transport,
		TAO_Queued_Message *	msg,
		ACE_Time_Value *	max_wait_time
	)			`[virtual]`

Wait until msg is sent out. Potentially other messages are flushed too, for example, because there are ahead in the queue.

Implements TAO_Flushing_Strategy.

int TAO_Reactive_Flushing_Strategy::schedule_output ( TAO_Transport * transport ) [virtual]

Schedule the transport argument to be flushed If -2 is returned then the caller must call one of the flush_* methods. If -1 is returned then there was an error. If 0 is returned then the flush was scheduled successfully.

Implements TAO_Flushing_Strategy.
