c ++密封和接口 [英] c++ sealed and interface

问题描述

我注意到，在C ++中有密封和接口关键字。这是CLR C ++吗？
如果没有，当被密封和接口添加到C ++标准？它们在C ++中有与在C＃中相同的意义吗？

I noticed that there are sealed and interface keywords in C++. Is this just for CLR C++? If not, when were sealed and interface added to the C++ standard? Do they have the same meaning in C++ as they do in C#? If not, how do I get the equivalent in standard C++?

推荐答案

密封和 interface 关键字仅用于C ++ / CLI。有关详情，请参见用于定位CLR的语言功能详细信息。

sealed and interface keywords are only for C++/CLI. See Language Features for Targeting the CLR for more details.

在标准C ++ 接口中，可以替换为纯虚拟类和多重继承。 密封的关键字可以替换为 boost :: noninheritable （这不是boost的官方部分）。

In standard C++ interface could be replaced with pure virtual class and multiple inheritance. Sealed keyword could be replaced with boost::noninheritable (which is not an official part of boost yet).
