Hello, my last message was a little sparse, so I thought I would provide some more detail.
In addition to looking into the the elephant:add-class-derived-index function, I also tried using the :derived-fn syntax (see: http://paste.lisp.org/display/85431 for an example of what I've attempted). I want to be able to use ele:get-instances-by-range on the derived slot ... Thanks, Shaneal _______________________________________________ elephant-devel site list elephant-devel@common-lisp.net http://common-lisp.net/mailman/listinfo/elephant-devel
