有没有一种方法可以在C ++中的类外部调用基本函数? [英] Is there a way to call a base function outside of the class in C++?

问题描述

此问题类似，但与从类内部调用函数有关:

This question is similar, but is about calling the function from inside the class: Can I call a base class's virtual function if I'm overriding it?

在这种情况下，您将指定Base::function()而不是function()，这将调用覆盖的定义.

In that case, you'd specify Base::function() instead of function(), which will call the overridden definition.

但是有没有办法在课堂之外做到这一点?我的类没有定义副本构造函数，所以我不知道如何将其转换为基类:

But is there a way to do this outside of the class? My class doesn't define a copy constructor, so I couldn't figure out how to cast as the base class:

Base( derived_object ).function()

在这里做适当的事情来将& derived_object转换为Base*然后调用->function()吗?

Is the appropriate thing to do here to cast & derived_object as Base* and then call ->function()?

感谢您的见识.

推荐答案

尝试derived_object.Base::function();
