This folder contains examples of using some of the built-in database
handling methods. Two hierarchies are provided, one prototype-based,
and the other class-based, in order to illustrate the differences
between asserting predicates in a class and in a prototype.
The following objects are defined:
root
root of the prototype hierarchy; declares and defines a public,
dynamic predicate
descendant
simple prototype extending the root prototype
class
root of the class hierarchy; declares and defines a public predicate
metaclass
class metaclass
instance
simple instance of class class
prototype
simple prototype used to illustrate how the scope of asserted
predicates depends on the target object (this, self, or a explicit
object)
