So I have been trying to learn the ins and outs of Racket's class system. I've a little puzzled when it comes to the "inherit"-forms. I've poured over the Racket Reference and fiddled with some experimental classes, but I'm still not clear.
My questions specifically are, What is the difference between inherit and inherit/super, and how does inherit/inner work? Below is a link to the page with the documentation in the Racket reference that I'm trying to understand, along with the pertinent paragraphs. Any help would be appreciated. Thanks! --Christopher http://docs.racket-lang.org/reference/createclass.html?q=class&q=arg-list-expr&q=define-values&q=contract-out&q=hash/c&q=match&q=cond&q=match&q=set-hash%21&q=let-values&q=list/c&q=is-a&q=listof&q=subclass&q=class/c&q=make-string&q=hash%3F&q=init-field&q=class/c&q=-%3E&q=chaperone&q=pos&q=positive&q=goto-line > 5.2.3.2 Inherited and Superclass Methods > > Each inherit, inherit/super, inherit/inner, rename-super, and > rename-innerclause declares one or more methods that are defined in the > class, but must be present in the superclass.
