Member Function Documentation

int TAO_Block_Flushing_Strategy::cancel_output

(

TAO_Transport *

transport

)

[virtual]

Cancel all scheduled output for the transport argument.

Implements TAO_Flushing_Strategy.

Definition at line 18 of file Block_Flushing_Strategy.cpp.

{
  return 0;
}

int TAO_Block_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.

Definition at line 24 of file Block_Flushing_Strategy.cpp.

References TAO_Queued_Message::all_data_sent(), and TAO_Transport::handle_output().

  while (!msg->all_data_sent ())

      if (transport->handle_output (max_wait_time) == -1)
        return -1;
    }
  return 0;
}

int TAO_Block_Flushing_Strategy::flush_transport	(	TAO_Transport *	transport,
		ACE_Time_Value *	max_wait_time
	)			[virtual]

Wait until the transport has no messages queued.

Implements TAO_Flushing_Strategy.

Definition at line 37 of file Block_Flushing_Strategy.cpp.

References TAO_Transport::handle_output(), and TAO_Transport::queue_is_empty().

{
  while (!transport->queue_is_empty ())

TAO_BEGIN_VERSIONED_NAMESPACE_DECL int TAO_Block_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.

Definition at line 12 of file Block_Flushing_Strategy.cpp.

{
  return MUST_FLUSH;
