The Liskov Substitution Principle

Abstract

This is the second of my Engineering Notebook columns for The C++ Report . The articles that will appear in this column will focus on the use of C++ and OOD, and will address issues of software engineer- ing. I will strive for articles that are pragmatic and directly useful to the soft- ware engineer in the trenches. In these articles I will make use of Booch’s and Rumbaugh’s new uni- fied notation (Version 0.8) for documenting object ori- ented designs. The sidebar provides a brief lexicon of this notation.
