c++ - 重载运算符 >> 像 std::cout

Question

我想创建一个类似于 std::cout 的类。我知道如何重载 >> 和 << 运算符，但我想重载 << 运算符，使其成为输入，就像在 std::cout 中一样。

应该是这样的:

class MyClass
{
   std::string mybuff;
 public:
   //friend std::???? operator<<(????????, MyClass& myclass)
   {
   }
}
.
.
.

  MyClass class;
    class << "this should be stored in my class" << "concatenated with this" << 2 << "(too)";

谢谢

Answer 1

class MyClass
{
    std::string mybuff;
 public:
    //replace Whatever with what you need
    MyClass& operator << (const Whatever& whatever)
    {
       //logic
       return *this;
    }

    //example:
    MyClass& operator << (const char* whatever)
    {
       //logic
       return *this;
    }
    MyClass& operator << (int whatever)
    {
       //logic
       return *this;
    }
};
