Look at the @ISA to see which classes are defined.

EXAMPLE:

@ISA = ( Module )

$self->SUPER::overridden_method(@_);

stop!! If you need the name of the superclass then there's almost certainly something conceptually wrong with your design. It should always sound alarm bells when you see class names occurring explicitly;

If you use the name of the superclass, you are denying yourself the ability to later swap in another object with the same interface which flies in the face of the object paradigm.

What would you to do with it if you did get it?

fishiface, the great thing is what I don't make the design, and I'm not making any aplications. There is a hierarcy of classes what I don't know, but the application is big, and have several bugs what I have to fix.

hey fishi how's it going, i'm thinking of picking up on that OO discussion we started.

Is it something you now have time for ?
