this is my class

**class Change { public: laser_geometry::LaserProjection projector;

    ros::NodeHandle n;
    ros::Publisher pub;
    ros::Subscriber sub;
    Change();
    void scanCallback(const sensor_msgs::LaserScan::ConstPtr& scan_in);
private:
    tf::TransformListener listener;

};**

any help appreciated!
