TAILIEUCHUNG - Lecture Systems analysis and design with UML (3/e) - Chapter 9: Class and method design

This chapter presents a set of criteria, activities, and techniques used to design classes and methods. Together they are used to ensure the object-oriented design communicates how the system needs to be coded. | Chapter 9: Class and Method Design Objectives Become familiar with coupling, cohesion, and connascence. Be able to specify, restructure, and optimize object designs. Be able to identify the reuse of predefined classes, libraries, frameworks, and components. Be able to specify constraints and contracts. Be able to create a method specification. BASIC CHARACTERISTICS OF OBJECT ORIENTATION Elements of OOSAD Classes Objects Attributes States Methods Messages Encapsulation & Info Hiding Hiding the content of the object from outside view Communication only through object’s methods Key to reusability Polymorphism & Dynamic Binding Same message triggers different methods in different objects Dynamic binding means specific method is selected at run time Implementation of dynamic binding is language specific Need to be very careful about run time errors Need to ensure semantic consistency Polymorphism Example Inheritance Single inheritance -- one parent class Multiple inheritance -- multiple .
