将类的引用返回到 this [英] Return reference from class to this

问题描述

我有以下 foo 类成员.

I have the following member of class foo.

foo &foo::bar()
{
   return this;
}

但我收到编译器错误.我做错了什么蠢事?

But I am getting compiler errors. What stupid thing am I doing wrong?

编译器错误 (gcc): 错误: 'foo&' 类型的非常量引用的无效初始化来自'foo* const'类型的临时数据

Compiler error (gcc): error: invalid initialization of non-const reference of type 'foo&' from a temporary of type 'foo* const'

推荐答案

this 是一个指针.所以应该是 return *this;

this is a pointer. So it should be return *this;
