The Theory of Classification, Part 12: : Building the Class Hierarchy

Abstract

The construction of specific object instances and the development of simple class hierarchy are discussed. The class hierarchy development includes recognizable classes, with mixtures of default, abstract and concrete methods. Generators that are extended into flexible object creation functions with initialization values passed to superclass functions, mimicking the behavior of real object-oriented languages. It is shown that the classes that are derived by inheritance give rise to objects of exact types, which match the expected interfaces of their superclasses and the separately-declared interfaces.
