boost 中的 noncopyable

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

class test : public noncopyable
{
};

int main()
{
 test a, b;
 // test b(a);
 // c = a;
}

這是通過繼承的方式來實現(xiàn)的 noncopy

也可以通過組合的方式

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

class test
{
private:
 noncopyable noncopyable_;
};

int main()
{
 test a, c;
 // test b(a);
 // c = a;
}
