C++11 有 C# 风格的属性吗? [英] Does C++11 have C#-style properties?

问题描述

在 C# 中，对于带有 getter 和 setter 的字段有一个很好的语法糖.此外，我喜欢允许我编写的自动实现的属性

In C#, there is a nice syntax sugar for fields with getter and setter. Moreover, I like the auto-implemented properties which allow me to write

public Foo foo { get; private set; }

在 C++ 中我必须写

In C++ I have to write

private:
    Foo foo;
public:
    Foo getFoo() { return foo; }

C++11 中是否有一些这样的概念允许我对此有一些语法糖?

Is there some such concept in the C++11 allowing me to have some syntax sugar on this?

推荐答案

在 C++ 中，您可以编写自己的功能.这是使用未命名类的属性的示例实现.维基百科文章

In C++ you can write your own features. Here is an example implementation of properties using unnamed classes. Wikipedia article

struct Foo
{
    class {
        int value;
        public:
            int & operator = (const int &i) { return value = i; }
            operator int () const { return value; }
    } alpha;

    class {
        float value;
        public:
            float & operator = (const float &f) { return value = f; }
            operator float () const { return value; }
    } bravo;
};

您可以编写自己的 getter &setter 就位，如果您想要持有者类成员访问权限，您可以扩展此示例代码.

You can write your own getters & setters in place and if you want holder class member access you can extend this example code.
