1. 禁止使用编译器默认生成的函数 假如上面的几个函数中,不想使用其中某个,可以将其定义为private,或者使用=delete。 #include<iostream>usingnamespacestd;classDataOnly{public:DataOnly() {} ~DataOnly() {}DataOnly(constDataOnly & rhs) =delete;//禁止使用该函数DataOnly &operator=(constDataOnly & rhs)...
//c++11 类默认函数的控制："=default" 和 "=delete"函数 /* C++ 的类有四类特殊成员函数，它们分别是：默认构造函数、析构函数、拷贝构造函数以及拷贝赋值运算符。这些类的特殊成员函数负责创建、初始化、销毁，或者拷贝类的对象。如果程序员没有显式地为⼀个类定义某个特殊成员函数，⽽⼜需要⽤到该特殊...

C++11 =default 和 =delete 1. = default 1.1 引入背景 C++ 的类有四类特殊的成员函数,分别为:默认构造函数,析构函数,拷贝函数以及拷贝赋值函数。如果程序没有显式地为一个类定义某个特殊成员函数,而又需要用到该特殊成员函数时,编译器会隐式地为这个类生成一个默认的特殊成员函数。
