Detailed Description

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.

Todo:

The class name (Sync_Strategy) is inherited from the policies (SyncScopePolicy), but Queueing_Strategy probably captures its intent better. It should be changed in a future revision of the ORB.

Member Function Documentation

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

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 1 if a timer should be set to drain the queue interval  If set_timer returns 1, this parameter contains the timer interval Reimplemented in TAO_Transport_Sync_Strategy, and TAO_Eager_Buffering_Sync_Strategy.

virtual int TAO_Sync_Strategy::must_queue (  int    queue_empty )  [pure virtual]

Return 1 if a message must be queued. Reimplemented in TAO_Transport_Sync_Strategy, TAO_Eager_Buffering_Sync_Strategy, and TAO_Delayed_Buffering_Sync_Strategy.
