A named KnowledgeWorks CLOS class is defined by the macro def-named-kb-class which is syntactically identical to the Common Lisp
defclass
macro, and semantically identical with the exception that it adds a KnowledgeWorks mixin class named-kb-object if none of the superclasses already contains it, and makes the default name for the objects be a symbol generated from the class name. Classes defined by def-named-kb-class contain a
name
slot which those defined by def-kb-class do not.
The function
make-instance
can be given the initialization argument
:kb-name
to specify a name. If not specified, a default name is generated from the name of the class. All names must be distinct as regarded by
eq
. The function
(get-kb-object <name>)
retrieves the instance from its name. The function
(kb-name <object>)
returns the name of the given object.
