public class UnitMap
extends Mapping

Java interface to the AST UnitMap class - unit (null) Mapping. A UnitMap is a unit (null) Mapping that has no effect on the coordinates supplied to it. They are simply copied. This can be useful if a Mapping is required (e.g. to pass to another function) but you do not want it to have any effect. The Nin and Nout attributes of a UnitMap are always equal and are specified when it is created.
