Subject-Oriented Programming (A Critique of Pure Objects)

Abstract

Object-Oriented technology is often described in terms of an interwoven troika of themes: encapsulation, polymorphism, and inheritance.But these themes are firmly tied with the concept of identity.If object-oriented technology is to be successfully scaled from the development of independent applications to development of integrated suites of applica-tions, it must relax its emphasis on the objecf.The technology must recognize more directly that a multiplicity of subjective views delocalizes the concept of object, and must emphasize more the binding concept of identity to tie them together.This paper explores this shift to a style of objectoriented technology that emphasizes the subjective views: Subject-Oriented Programming.
