将getter和setter设置为内联代码是一种好习惯吗？ [英] Is it good practice to make getters and setters inline?

问题描述

public:
     inline int GetValue() const {
          return m_nValue;
     }
     inline void SetValue(int nNewValue) {
          this -> m_nValue = nNewValue;
     }

在 Learn C ++ 上，他们说它将运行快点。因此，我认为在getter和setter上使用它会很棒。但是，也许有一些缺点吗？

On Learn C++, they said it would run faster. So, I thought it would be great to use on getters and setters. But maybe, there are some drawbacks to it?

推荐答案

在分析器明确告诉我之前，我什么都不要内联内联会导致性能问题。

I don't inline anything until a profiler has specifically told me that not inlining is resulting in a performance problem.

C ++编译器非常聪明，几乎可以肯定会自动为您内联这样的简单函数。通常，它比您更聪明，并且在确定应内联或不应该内联的内容方面会做得更好。

The C++ compiler is very smart and will almost certainly automatically inline such simple function like this for you. And typically it's smarter than you are and will do a much better job at determining what should or should not be inlined.

我会避免考虑要插入或不插入什么内容并专注于解决方案。稍后添加 inline 关键字（不保证inline BTW）非常容易，并且可以使用探查器轻松找到潜在的位置。

I would avoid thinking about what to or not to inline and focus on the solution. Adding the inline keyword later (which is not a guarantee of inline BTW) is very easy to do and potential places can be found readily with a profiler.
