Anonamously referencing procedures within a class

-----------------------------------

I don't know if I used the terminology right there, but eh.


class Stuff
export WriteThis

   procedure WriteThis (s : string)
      put s
   end WriteThis
   procedure WriteFirstCharacter (s : string)
      put s(1)
   end WriteFirstCharacter
end Stuff


Allright, now if I wanted to anonamously reference that procedure, is there any way to go about doing that?


%Imaginary Syntax to show what I want to do
var q : array 1..2 of procedure p (s : string)
q(1) := Stuff.WriteThis
q(2) := Stuff.WriteFirstCharacter


Is there any possible way to do this?  I've tried creating a pointer to the class, and assigning q to the procedure that way, but it didn't work...

I understand what you're asking.  I believe what you're looking for is an abstract class, or an abstract procedure, however, since I've never looked into Turing classes, I'm not sure if they exist in Turing.

No, you can't do that. The reason being that those procedures only exist for instances of the Stuff class, not for the class itself.

What you're looking for is a .

Darn. Thanks for your help man.  A module wouldn't be useful in the instance I was asking this about.  (Unfortunately, I forgot the instance  :oops:  I was trying to figure out a way around it for like a week, so I finally gave up and posted the question on here, for future reference, but I can't remember what the actual instance of it was...)
