yes.
In other words, using the C++ paradigm, you could have
class test{
private:
this_isnt_so_private();
public:
write(int);
int read();
}
Or, using the java paradigm, you could have
class test implements writeread
{
/* truely hidden stuff */
}
Interface writeread
{
write(int);
int read();
}
NOTE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I did this off the top of my head. the java syntax is probably not correct.
Forget about multiple inheritance. The real beauty of this, is that
unlike C++, you no longer have to distribute a .h file, that contains
more information about the class than you would like to share.
Plus, you can interface to potentially ANY object, not just an object which
happens to be a subclass of "X".
