Concept-Oriented Programming - Classes and Inheritance Revisited

摘要

The main goal of concept-oriented programming (COP) is describing how objects are represented and accessed. References (object locations) in COP are made first-class elements responsible for many important functions which are difficult to model via objects. COP rethinks and generalizes such primary notions of object-orientation as class and inheritance by introducing a novel construct, concept, and a new relation, inclusion. They make it possible to describe many mechanisms and patterns of thoughts currently belonging to different programming paradigms: modeling object hierarchies (prototype-based programming), precedence of parent methods over child methods (inner methods in Beta), modularizing cross-cutting concerns (aspect-oriented programming), value-orientation (functional programming).
