功能模板的部分专业化 [英] partial specialization of function template

问题描述

任何人都可以解释为什么部分专业化对函数模板无效，但对类模板来说很好。

Can anybody explain why partial specialization is not valid for function template but it's fine for class template.

我理解部分专门化可能会使编译器与函数重载混淆，但是我仍然需要更多的信息让我完全理解。

I understand partial specialization might make the compiler get confused with function overloading, but I still need more information to make me totally understand. Can anybody offer me some neat examples?

推荐答案

在这种情况下，困惑就足够了。

Getting confused is enough of a reason, in this case.

还有一个现有的替代解决方案：重载。委员会花了很多努力（在我看来，我不在那里）获得函数重载解析工作的模板，肯定的一部分原因包括不必解决较不通用的，硬的问题的功能模板部分专业化。

And there's an existing alternative solution: overloading. The committee spent a lot of effort (it seems to me, I wasn't there) getting function overload resolution working for templates, and surely part of the reason for that included not having to solve the less-general, hard problem of function template partial specialization.
