C++ 编写一个不可复制的类

flyfish

Effective C++:条款06
若不想使用编译器自动生成的函数，就该明确拒绝 .
Explicitly disallow the use of complier-generated functions you do not want.


老式C++的写法

class noncopyable
{
protected:
	noncopyable() {}
	~noncopyable() {}
private:
	noncopyable( const noncopyable& );
	noncopyable& operator=( const noncopyable& );
};

class noncopyable
{
protected:
	constexpr noncopyable() = default;
	~noncopyable() = default;
	noncopyable( const noncopyable& ) = delete;
	noncopyable& operator=( const noncopyable& ) = delete;
};

	namespace boost {
		namespace noncopyable_ 
		{
			class noncopyable
			{


			};
		}
		typedef noncopyable_::noncopyable noncopyable;


}
