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