C++扩展类强制某些方法私有(private)

Question

我的问题很简单:~给定两个类，我希望其中一个扩展另一个，但将一些方法变成私有(private):

Class B
public Method a();
public Method b();
public Method c();

Class A extends B
private Method a();
private Method b();
public Method c();

这可能吗？如何实现？ 谢谢!

Answer 1

这就是私有(private)继承的用途。

class A:   private B
{
    // All methods of class B are now private.
    // To make some "public" again:
    public:
        Method c()  { return B::c(); } // Call the private c-method from class B.
};
