问题描述
我有类似的东西(简化)
I have something like that (simplified)
class A
{
public:
virtual void Function () = 0;
};
class B
{
public:
virtual void Function () = 0;
};
class Impl : public A , public B
{
public:
????
};
如何实现A的Function()和B的Function
Visual C ++让你只能定义特定的函数inline(即不在cpp文件中),
,但我想它是一个扩展。 GCC抱怨这个。
是否有标准的C ++方法告诉编译器我要覆盖哪个函数?
How can I implement the Function () for A and the Function() for B ?Visual C++ lets you only define the specific function inline (i.e. not in the cpp file),but I suppose it's an extension. GCC complains about this.Is there a standard C++ way to tell the compiler which function I want to override?
(visual c ++ 2008)
(visual c++ 2008)
class Impl : public A , public B
{
public:
void A::Function () { cout << "A::Function" << endl; }
void B::Function () { cout << "B::Function" << endl; }
};
谢谢!
推荐答案
您不能在那里使用限定名称。我写了 void Function(){...}
你正在覆盖两个函数。 Herb Sutter会显示。
You cannot use qualified names there. I you write void Function() { ... }
you are overriding both functions. Herb Sutter shows how it can be solved.
另一种选择是重命名这些函数,因为显然他们做了不同的事情(否则我看不到重写行为)。
Another option is to rename those functions, because apparently they do something different (otherwise i don't see the problem of overriding both with identical behavior).
这篇关于C ++虚拟覆盖函数具有相同的名称的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
