Prevent Derivation (Cross Ref > Tool Basics)

By Mike Prestwood

C++/CLI versus VB Classic: A side by side comparison between C++/CLI and VB Classic.

OOP Details

More object oriented (OO) stuff.

Prevent Derivation

[Other Languages]

Languages Focus

How do you prevent another class from inheriting and/or prevent a class from overriding a member.

C++/CLI: sealed

VB Classic: Not Supported

VB Classic supports a form of single level inheritance where you, in essence, create an abstract class and then implement it in one or more classes that inherit from the abstract class. However, you cannot have any further descendant classes so "prevent derivation" is implemented by design of this simple inheritance model.
