C ++：如何设计实用程序类？ [英] C++: How to design a utility class?

问题描述

但是我不知道我应该去静态方法，只是一个标题，一个类，或者别的什么？

But I don't know if I should go for static methods, just a header, a class, or something else?

什么是最佳实践？但是，我不想有一个实用程序类的实例。

What would be best practice? But, I don't want to have an instance of a utility class.

我想添加如下函数：

Uint32 MapRGB (int r, int g, int b);
const char* CopyString(const char* char);
// etc. You know: utility methods...

推荐答案

不要把它们放在类中;

Don't put them in a class; just make them non-member functions at namespace scope.

没有规则说每个函数都必须是某个类的成员函数。

There's no rule that says every function has to be a member function of some class.
