如何使用宏#define更改类名？ [英] how to use macro #define to change class name?

问题描述

我有一个类

 class A{}

但我想使用宏用以下语句替换类名A：

But I want to use macro to replace the class name A with the following statement:

#define SOMETHING A

class A {} 的定义与MACRO在同一个.cpp中。

The definition of class A {} is in the same .cpp with the MACRO.

是否正确？

我想这样做，因为我删除了源代码中的所有MACRO。但是MACRO被广泛使用。

I want to do this, because I am removing all of the MACRO in the source code. But the MACRO was used widely. Does any software could help me to do the replacement of MACRO ?

推荐答案

颠倒令牌; #define A SOMETHING 应该工作。

Reverse the tokens; #define A SOMETHING should work.

请注意，这是一个可怕的想法，因为它可能会破坏其他代码和混淆

Note that it is a terrible idea as it may break other code and confuse the hell out of people.

使用别名：

class A { … };
using SOMETHING = A;
