public void setReferenceSystem(int system)

Description copied from interface: CartographicSupport

Sets the Reference System that defines how this units have to be handled. Possible values are:

If ReferenceSystem is CartographySupport.PAPER, and the length is (e.g.) millimeters the element will be displayed with the same amount of millimeters of length whether in the screen or the printer (screen DPI and printer DPI must be correctly configured).
