JScript .NET, Part IV: Inheritance

A Final Word

In this column we described JScript .NET's support of inheritance. Inheritance is probably not as important as encapsulation to object oriented programming languages, but is still a very important motive of these languages. We showed you how to extend base classes to derived classes, how to implement functions of interfaces, how to force extension by abstract, and how to avoid it by final. We taught you how to override base class methods with derived classes with override and hide, and how to avoid it with final.

In this column you have learned:

• How to extend a base class
• How to write an interface
• How to mark class members as abstract
• How to specify the overriding rules
• How to avoid overriding with final
