Error: invalid use of template-name ‘geometry_msgs::Pose_’ without an argument list

edit

Hi,

I'm trying to create a method:

  geometry_msgs::Pose_::_orientation_type rotationVectorToQuaternion(geometry_msgs::PointStamped::_point_type rotVec, double angle) {

    geometry_msgs::Pose_::_orientation_type quaternion;
    return quaternion;

  }

To set value to:

geometry_msgs::PoseStamped poseStamped;
poseStamped.pose.orientation = rotationVectorToQuaternion(message, angle);

However i get this error:

error: invalid use of template-name ‘geometry_msgs::Pose_’ without an argument list
   geometry_msgs::Pose_::_orientation_type rotationVectorToQuaternion(geometry_msgs::PointStamped::_point_type rotVec, double angle)

This is a cpp thing, but I need some help with it.
