Member Function Documentation

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.

References TAO_Transport::cancel_output_i(). 

00024 {

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.

TAO_BEGIN_VERSIONED_NAMESPACE_DECL 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.
