Public Member Functions | |
| virtual | ~Transport_Queueing_Strategy (void) |
| Destructor. | |
| virtual bool | must_queue (bool queue_empty) const =0 |
| Return true if a message must be queued. | |
| virtual bool | buffering_constraints_reached (TAO_Stub *stub, size_t msg_count, size_t total_bytes, bool &must_flush, const ACE_Time_Value ¤t_deadline, bool &set_timer, ACE_Time_Value &interval) const =0 |
| Return true if it is time to start. | |
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.

Return true if it is time to start.
| 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.
