Description

For object-oriented programming courses in Smalltalk or as a supplement to concepts of programming language or software engineering courses using Smalltalk.

Designed to bridge the gap between well-established software engineering principles and the actual practice of programing in an OOP language such as Smalltalk, this text documents a minimal set of guidelines and potential standards in design techniques that promote easy reuse and maintenance of object-oriented code, reduce the number of defects, and make code easier to read.


Features

  • uses Smalltalk vocabulary and examples, however most of the concepts are generic and directly applicable to other object-oriented languages.
  • presents a set of specific guidelines for using Smalltalk in a disciplined manner. Each guideline consists of a concise statement of principles and examples.
  • addresses layout and structure — including overall program structure.
  • considers the level of comments needed in a project.
  • discusses reliability and portability issues.
  • excellent, inexpensive course supplement.
