Detailed Description

Define the interface for the Queueing Strategy.

The low-level I/O components in the ORB use this strategy to determine when messages must be queued, immediately sent or flushed.

The strategy isolates this low-level components from the higher level strategies used by the application developer.

Member Function Documentation

virtual bool TAO::Transport_Queueing_Strategy::buffering_constraints_reached (  TAO_Stub *  stub, size_t  msg_count, size_t  total_bytes, bool &  must_flush, const ACE_Time_Value &  current_deadline, bool &  set_timer, ACE_Time_Value &  interval )  const [pure virtual]

Return true if it is time to start. Parameters: stub  The object used to make the request, this is used to obtain the policies currently in effect for the request msg_count  The number of messages currently queued total_bytes  Number of bytes currently queued set_timer  Returns true if a timer should be set to drain the queue interval  If set_timer returns 1, this parameter contains the timer interval must_flush  Is set to true if things must be flushed at this moment Implemented in TAO::Default_Transport_Queueing_Strategy, TAO::Flush_Transport_Queueing_Strategy, and TAO::Eager_Transport_Queueing_Strategy.

virtual bool TAO::Transport_Queueing_Strategy::must_queue (  bool  queue_empty  )  const [pure virtual]

Return true if a message must be queued. Implemented in TAO::Default_Transport_Queueing_Strategy, TAO::Flush_Transport_Queueing_Strategy, TAO::Eager_Transport_Queueing_Strategy, and TAO::Delayed_Transport_Queueing_Strategy. Referenced by TAO_Transport::send_asynchronous_message_i().
