获取当前类的typedef [英] Get typedef of current class

问题描述

我目前正在使用boost :: intrusive_ptr和我的GUI类。
虽然这或多或少是一个方便的问题，是否有正确的方法来获取当前类的typename？
我要求的原因是我有一个宏用于typedef的不同的指针类型：

I'm currently using boost::intrusive_ptr together with my GUI classes. Although this is more or less a convenience question, is there a proper way to get the typename of the current class? The reason I'm asking is that I have a macro for typedef'ing the different pointer types:

#define INTRUSIVE_PTR_TYPEDEFS(CLASSNAME) typedef boost::intrusive_ptr<CLASSNAME> Ptr; \
typedef boost::intrusive_ptr<const CLASSNAME> CPtr; \
typedef CLASSNAME* WeakPtr; \
typedef const CLASSNAME* CWeakPtr;

...

class Widget
{
public:
    INTRUSIVE_PTR_TYPEDEFS(Widget);
    ...
};

class Button : public Widget
{
public:
    INTRUSIVE_PTR_TYPEDEFS(Button);
    ...
};

CLASSNAME 自动推导出来，所以你可以简单地将它粘贴到类体中。我使用Visual Studio 2010附带的编译器。

It would be much more comfortable to have CLASSNAME automatically deduced so you could simply copy'n'paste it into the class body. I'm using the compiler shipped with Visual Studio 2010.

提前感谢！

推荐答案

不，这是不可能在C ++中做的。

No, that's not possible to do in C++.
