Eiffel Control Instructions,Previous chapters have introduced three types of instruction:

MOTTO

Bricklayer

CHURL

Inheritance,This chapter introduces single inheritance; it also covers the concept of polymorphism, the rules for conformance in Eiffel, and the related topic of reverse assignment. It concludes with a discussion of when inheritance is and is not appropriate.

Generic Classes,The term genericity is clearly related to the word ‘general’, and when we talk of genericity in the context of software construction we are talking about the capacity to produce components which have a general use. Such components are essential if we are to promote the reuse of code through the development of class libraries.

Multiple and Repeated Inheritance,Previous chapters have introduced single inheritance, and have looked at the ways in which the features of inherited classes may be altered by descendant classes. This chapter completes the study of inheritance by introducing multiple and repeated inheritance.

Case Studies,This chapter provides two case studies. The first builds on classes developed in the chapters on generic and abstract classes. The second, more complex study, implements a back propagating neural network from scratch. The chapter also illustrates the use of CRC cards in object-oriented design.
