How to set input cloud for pcl::BoxClipper3D

My pcl version is 1.8. I plan to use pcl::BoxClipper3D to remove the points inside a box.As there is an angle between the box and the x-axis of point cloud, pcl::cropbox cannot used directly.So I choose pcl::BoxClipper3D. However there is no member method to set input cloud because it not inherit from Filter. So anyone have idea to use pcl::Boxclipper3D to filter points inside a certain box?
