ps: the sample code from mark blewett looks very promising?
Yes. Although from my point of view, it has the same drawback with switching on messages that you have. I wonder if the queue of messages in the servant class could be a queue of fully-bound function calls,
I'm halfway there, in that the queue holds callbacks, eg in Servant::dispatch the "do something with m" simply executes the callback. To give a usage example class MyServant : public Servant { public: MyServant(Scheduler* scheduler) : Servant(scheduler) {} void do_fn(int x, int y) { std::cout << x << " " << y << std::endl; } }; int main() { Scheduler scheduler; scheduler.start(1,1); MyServant my_servant(&scheduler); my_servant.post_call(new CallbackVAA<MyServant,int,int>(&my_servant, &MyServant::do_fn, 1, 2)); scheduler.stop(); return 0; } will result in the output "1 2" via one of the schedulers worker threads
generated by proxy objects which describe interfaces? (Yes, I am quite enamoured of that idea :))
Interesting idea... assuming I'm understanding correctly.. in that the callback is created by an object in the servant class, the above becomes; class MyServant : public Servant { public: MyServant(Scheduler* scheduler) : Servant(scheduler), fn(this, &MyServant::do_fn) {} MethodProxy<MyServant, int, int> fn; private: void do_fn(int x, int y) { std::cout << x << " " << y << std::endl; } }; int main() { Scheduler scheduler; scheduler.start(1,1); MyServant my_servant(&scheduler); my_servant.fn(1, 2); // certainly a lot easier to understand than previous example! scheduler.stop(); return 0; } Regards Mark --- Outgoing mail is certified Virus Free.
