Hi all,
I've been banging my head against this for hours and am now at a loss.
I have:
class A
...
feature
c: INTEGER
...
end -- A
I want to replace this attribute c in a subclass with a method:
class B
inherit
A
rename
c as c_int -- so all the features that manipulate c in the
superclass still work fine when inherited, and I can get at it too
redefine
c -- because I want to redefine it here
end
...
feature
my_other_A: A
c: INTEGER is
do
result := c_int + my_other_A.c
end -- c
end -- B
I cannot get this to work. First, if I included the redefine clause in
B as above it won't compile - fair enough, I have renamed c, so it's
not around for me to redefine. I can just give a new definition for c,
I would think...
... but no. After removing the redefine clause, everything compiles
sweetly, but it does not work. Using the debugger, it seems that
routine c is never entered for objects of class B. It is just
returning the integer that I renamed c_int.
Surely there is a way of overriding an attribute with a method? Isn't
Eiffel supposed to have a Uniform Access Principle?
I am at a loss...
Thanks,
David
