问题描述

显式模板实例化是否在 cpp 或头文件中?

Does explicit template instantiation go in cpp or header file?

推荐答案

我一直在 cpp 文件中完成.在标头中，至少(在通常情况下)当标头包含在多个 cpp 文件中时，它会违反一个定义规则.

I've always done it in a cpp file. In a header, it would violate the one definition rule, at least (in the usual case) when the header was included in more than one cpp file.
