int TAO_Leader_Follower_Flushing_Strategy::cancel_output

(

TAO_Transport *

transport

)

[virtual]

Cancel all scheduled output for the transport argument.

Implements TAO_Flushing_Strategy.

Definition at line 24 of file Leader_Follower_Flushing_Strategy.cpp.

References TAO_Transport::cancel_output_i().

{
  return transport->cancel_output_i ();

		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.

TAO_BEGIN_VERSIONED_NAMESPACE_DECL int TAO_Leader_Follower_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.
