The "typical" way of doing this is via a comparison function and a generic sort routine. So you provide a function that compares two objects and returns their order. The order is often returned as in integer with -1 meaning the first is lesser, 0 meaning they are equal, and +1 meaning the second is lesser.
Then you have some generic sort routine that accepts a collection of objects and your comparison function. That routine does it's sort using your function for all comparison operations. I'm not sure where such a generic sort routine exists (at least in CF), but that's the general idea. cheers, barneyb On 8/20/07, Justin Treher <[EMAIL PROTECTED]> wrote: > I'm doing the OOP thing with the help of many tutorials from all over. > > I've run into a stump.
