Description

Defines a new CLOS class as defclass does. However, if none of the given superclasses is a subclass of named-kb-object, then named-kb-object is added to the list of superclasses. The class inherits a name slot kb-name of which the initialization form (:initform) generates a symbol from the class name using (gentemp class-name).

Examples

(def-named-kb-class vehicle ()

  ((driver :initarg :driver)))

(def-named-kb-class truck (vehicle)

  ((load :accessor truck-load)))
