在自身内部调用类函数/运算符 [英] Calling a class function/operator within itself

问题描述

Heya，

对于研究图形编辑C ++项目，我需要一种定义和处理2D数组的简单方法.我添加了一个类，该类定义了大小为x * y的一维数组，但可以进行寻址并类似于二维数组.

Heya,

For a study graphics editing C++ project, I was in need of a simple way of defining and addressing 2D arrays. I added a class that defines a 1D array of the size x*y, but can be addressed and works similary to a 2D array.

Point* operator[](int x)
    {
        return & ARR[x * Y];
    }

通过使用operator方法，我可以轻松地从外部访问这些点.现在我的问题是，如何在类内部使用运算符.

例如，我想创建一个用于计算所有点的平均RGB值的类，但是如何在该类中使用运算符，该运算符的定义在?

With the use of the operator method, I can easily access the points from outside. Now my problem is, how do I use the operator from inside the class.

For example I want to create a class that calculates the avarage RGB value of all points, but how can I use the operator within the class, it was defined in?

推荐答案

我猜想这个(* this)[]可以.. ??

i guess this (*this)[] will do ..?

您也可以使用功能符号，例如

You may also use the function notation, e.g.

operator[](5);
