你认为它是合法的模板;我b / b
尝试了练习并且编译失败但我会再次阅读我的模板

我无法让它工作。我会说它不能被模板化

因为试图给衍生类授予友谊的问题，

但我可能是错的。

I know I have seen some threads on the subject long time ago and it
was using a virtual base class ...

in short, what is the nicest way to implement the Java final class in
c++

Thanks.

Thanks John; I was actually thinking on that path, however, I am
trying to templatize the idea. Do you think it is template legal; I
tried the exercise and failed compiling but I will read my template
book again.

I couldn''t get it to work either. I would say it cannot be templatized
because of the problem of trying to grant friendship to the derived class,
but I could be wrong.
