What Every Programmer Should Know About Object-Oriented Design

If you're a programmer using C++, Smalltalk, or Eiffel, or if you're about to migrate to object orientation for the first time, you need to know the most important principles of object-oriented design.

For example: In a reliable design, why must a variable's cone of polymorphism lie within that of a method. Is connascence good or bad? How could the inherited methods of a superclass violate the invariant of a subclass -- and how can this be prevented?

Page-Jones answers these questions and more, with characteristic clarity, demystifying the fundamentals of object orientation in a language-independent way. He provides a comprehensive notation for object-oriented design that allows you to depict the design for a whole system or to jot down back-of-the-envelope ideas. features 150+ diagrams and exercises Topics Include
