public class Domain
extends java.lang.Object

This class defines a partition of an interval into subintervals of equal width. These objects are used to define default domains. A finite domain can be modeled by the values (midpoints) of the partition. The boundary points are a + i * w for i = 0, ..., n, where n is the size of the partition, a is the lower bound and w the width. The values (midpoints) are a + (i + 1/2) * w, for i = 0, ..., n - 1.
