.inl文件在C ++中的意义 [英] Significance of a .inl file in C++

问题描述

在.inl文件中声明的优点是什么？何时需要使用相同的？

What are the advantages of having declarations in a .inl file? When would I need to use the same?

推荐答案

.inl 从不是强制性的，对编译器没有特殊意义。

.inl files are never mandatory and have no special significance to the compiler. It's just a way of structuring your code that provides a hint to the humans that might read it.

我使用 .inl 文件的两种情况：

I use .inl files in two cases:

• 有关内联函数的定义。


• 模板。

在这两种情况下，我将函数的声明放在头文件中， #include 头文件底部的 .inl 文件。

In both cases, I put the declarations of the functions in a header file, which is included by other files, then I #include the .inl file at the bottom of the header file.

我喜欢它，因为它将接口与实现分离，并使头文件更容易阅读。如果你关心实现细节，你可以打开 .inl 文件并读取它。如果你不这样做，你不必。

I like it because it separates the interface from the implementation and makes the header file a little easier to read. If you care about the implementation details, you can open the .inl file and read it. If you don't, you don't have to.
