问题描述

从派生类的运算符中调用运算符的正确方法是什么?

What's the correct way to invoke an operator from within the derived class's operator?

我正在尝试从派生类的重载运算符中调用基重载运算符.我尝试了以下但似乎不起作用:

I'm trying to call a base overloaded operator from within the derived class's overloaded operator. I tried the following but it doesn't seem to work:

const myObject& myObject::operator = (const myObject &otherObject) {
static_cast<BaseType>(*this) = static_cast<BaseType>(otherObject); // assuming BaseType has assignment overloaded
return *this;
}

这是实际代码:

const studentType& studentType::operator = (const studentType &student) {
  static_cast<personType>(*this) = static_cast<personType>(student);

  // new junk here

  return *this;
}

注意:基类的运算符已重载，因此没有问题.

Note: The base class's operator is overloaded, so no issues there.

推荐答案

使用以下代码

const studentType& studentType::operator = (const studentType &student) {
  personType::operator =(student);

  // new junk here

  return *this;
}
