在模板类的头文件中包含.cpp文件 [英] Including .cpp file in the header file for a template class

问题描述

我知道模板类的定义和实现应该在同一个头文件。但我在学校上学的有点不同。

I do know that template class's definition and implementation should be on the same header file. But I was taught a bit differently at school.

我会在头文件中定义模板类，在头文件的末尾， do #includeMyFile.cpp，它包含模板类的实现。

I'll have the template class's definition in the header file, and at the end of the header file, I'll do #include "MyFile.cpp", which contains the implementation of the templated class.

这是坏的编程实践吗？

一般来说不是，这是一个很常见的技术。但问题是 .cpp 文件扩展名，这将影响许多IDE和构建系统，将其视为常规源文件。更常用的扩展名为 .tcc ， .tpc 。

In general not and it's a very common technique. But the problem is the .cpp file extension, that would affect many IDEs and build systems to consider it as a regular source file. More commonly used extensions are .tcc, .tpc.
