What if you have a subclass of com.truck named com.compacttruck and need to know if that class can tow a boat? You'll need to ascend the object hierarchy and check every level. Check my UDF from the first post I made in this thread for an implementation.
Really, this problem pretty much requires interfaces to solve elegantly, but we don't have them with CFCs. The vibe I get is that it's never going to change, which is unfortunate, but such is life. You could use synthesized interfaces (an 'implements' attribute in the CFCOMPONENT tag) to do typechecking, but you'd obviously not get any of the compile-time benefits. cheers, barneyb On Apr 6, 2005 1:25 PM, Roland Collins <[EMAIL PROTECTED]> wrote: > > Instead of asking the car what type of car it is, why don't you just > >ask it whether it can tow boats? > > > ><cfif myCar.canTowBoats()> > > The only problem with this is flexibility.
