完成虚拟方法 [英] Finalizing virtual methods

问题描述

大家好，


假设我有一个类（让我们用A类调用A类）。

然后定义一个子类（B），它可能会被某些

其他子类（比方说，C）扩展。因此，A< -B< -C。我想以与最终的方式相同的方式来防止C重新定义虚拟方法。 Java中的方法

无法覆盖..有没有办法在C ++中执行此操作？


Dave。

Hi all,

Suppose that I have a class (let''s call the class A) with a virtual method.
I then define a subclass (B), which could potentially be extended by some
other subclass (say, C). So, A <- B <- C. I want to prevent C from
redefining the virtual method in same manner as how a "final" method in Java
cannot be overridden.. Is there some way to do this in C++?

Dave.

否。为什么要这样做？

No. Why would you want to do that?

文档，这是唯一的方法。或者选择另一种语言，也许是从字母J开始的

Documentation, its the only way. Or choose another language, perhaps
beginning with the letter J.
