RE: dia2code objc

[Mondragon, Ian]

just my 2 cents here, but this is NOT C++.  if you want to have particular
ivars of a class accessable by other classes, yet at the same time have them
protected or private, you will have to do one of the following:

        1. implement accessor methods
        2. have a common superclass

there is no "friend" specifier in objective-c (thank god.  what a stupid
name, too...).  in fact, "friend" is just a way of escaping data hiding
restrictions in select cases, but if you're going to need to do it once,
you'll probably need to do it again.  just create an accessor method.

ps - at least it's not called "buddy".  bwaaaahaaahaaa...
