This is reasonable question. If that happens, we will sooner of all have to add new types of provider interface, and support 2 types of them for a while (at least one ODS version). > Sorry, but if you want > nitpicking, I can continue which such type of question. Adriano, I do not wnat nitpicking. Moreover, I agree that my commit was (not to say more) bad. But your initial solution with non-POD objects in API was also bad. I have not understood - do you see problems with replacing C++ classes with POD objects, i.e. structures, in interface? ------------------------------------------------------------------------------ Forrester Wave Report - Recovery time is now measured in hours and minutes not days.
