[HELP] : about class variables

[kurk_lord]

Hi all,

in ruby class variables are private. Who know to do
for making them accessible to the outsite world. I
am looking for to do something like in Java :

Toto.count

Toto is my class and count is my class variable.

Thanks all,

You could do:

class Toto
def Toto.count
@@count
end
end

As an Object, a Class is also entitled to have its own instance
variables. So you also use @count in the above, rather than @@count.
(And actually @count has some advantages, in terms of scope. It
actually *more* private to the class -- but still can be made visible
through a method, if the class wants it to be.)
