如果派生类有同名的方法，如何从派生类调用基类方法？ [英] how do I call a base class method from the derived class, if the derived class has a method with the same name?

问题描述

这是我想要能够做的:(伪代码）

this is what I want to be able to do: (pseudo code)

class DerivedClass : public BaseClass
{
    public Draw()
    {
        BaseClass.Draw()
    }
}

class BaseClass
{
    protected Draw();
}

两个绘图都有相同的名称和相同的签名。想要这样做的原因是，有时我想要我的派生类有一个绘制函数，只是调用基类绘制，但在其他时候，我想让派生类选择什么时候调用基本绘制函数或不。这意味着我可以保持我实例化派生类更清洁的类，并可以在所有时间调用它们的所有。派生类本身处理nitty-gritty。

Both draws have the same name and the same signature. The reason for wanting to do this is that sometimes I want my derived classes to have a draw function that simply calls the Base Classes draw, but at other times I want the derived class to choose when to call the base draw function or not. This meant that I can keep the class that I instantiate the derived classes in much cleaner, and can just call draw on all of them at all times. The derived classes themselves handle the nitty-gritty.

BaseClass.Draw 部分的语法究竟是什么？我想你可能只是写的，因为它是，但编译器抱怨，它不像我可以调用 Draw ，因为签名是相同的。

What exactly is the syntax for the BaseClass.Draw part? I thought you could actually just write that as it is, but the compiler is complaining, and it's not like I can just call Draw because the signatures are the same.

推荐答案

语法是 BaseClass :: Draw（）。
