java.lang.Object	getSingleRef(M4Object parameter) The M4Object different from the container object needs to have a reference to the container class.
void	setSingleRefPrimitive(M4Object parameter, java.lang.Object paramObj) The M4Object different from the container object needs to have a reference to the container class.
