Thus ACE_Upcall_Strategy becomes a + vehicle for extending the behavior of ACE_Timer_Queue wrt the + upcall (callback) *without subclassing*.

This + new scheme allows any of the threads in the "thread pool" + waiting on the completion port of the Proactor to execute the + callback routine of the handler. + + The implementation included adding ACE_Proactor_Timer_Handler + class that has a thread that will wait on the earliest time in a + timer queue and an event. When a timer expires, the thread will + post a completion event on the port and go back to waiting on + the timer queue and event. If the event is signaled, the thread + will refresh the time it is currently waiting on (in case the + earliest time has changed). + + The ACE_Proactor::Asynch_Timer class is posted to the completion + port when a timer expires. When the <complete> method of this + object is called, the <handler>'s handle_timeout method will be + called. + + * examples/Reactor/Proactor/test_timeout: This example illustrates + the new timer features in the Proactor + + * examples/Reactor/Proactor/test_proactor.{mdp,mak}: Added new + example. + Tue Apr 22 00:21:03 1997 Douglas C.
