Chapter 4
Object-Oriented Programming

Overview

The object-oriented programming style is becoming increasingly popular. It promises code reuse and easier maintenance of larger projects than is possible with traditional procedural languages. Its use of methods and message passing instead of procedure calls shifts the programmer's view toward close integration of data and operations. An interactive object-oriented language can easily be implemented in Mathematica. In the last chapter we discussed two important tools, message passing and objects. We now present the other tools, classes and inheritance. To illustrate the programming style we expand the example developed in the last chapter and give an implementation of collections.
