Description

The macro def-named-kb-class defines a new CLOS class name class-name, as defclass does. However, if none of the superclasses in superclass-list is a subclass of named-kb-object, then named-kb-object is added to the list of superclasses. The class inherits a name slot called kb-name, with accessor kb-name and default initialization form (:initform) that generates a symbol from the class name using (gentemp class-name).

slot-descriptions and options are used as in the standard defclass macro.

Examples

(def-named-kb-class vehicle ()
  ((driver :initarg :driver)))
(def-named-kb-class truck (vehicle)
  ((load :accessor truck-load)))
