boost中的noncopyable

继承noncopyable的类，不允许拷贝构造和赋值。省去了，每次手动把类的拷贝构造和赋值函数写在private下

头文件: #inlucde <boost/noncopyable.hpp>

class noncopyable  {   protected:      noncopyable() {}      ~noncopyable() {}   private:  // emphasize the following members are private      noncopyable( const noncopyable& );      const noncopyable& operator=( const noncopyable& );  };
