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.

Constructor Summary

Domain()
This default constructor creates a new partition of [0, 1] into 10 equal subintervals

Domain(double b)
This special constructor creates a new partition of [0, b] into 10 equal subintervals

Domain(double a, double b, double w)
This general constructor creates a new partition of a specified interval [a, b] into subintervals of width w

Method Summary

double	getBound(int i) This method returns the boundary point corresponding to a given index
int	getIndex(double x) This method returns the index of the interval containing a given value of x
double	getLowerBound() This method returns the lower bound
double	getLowerValue() This method returns the lower midpoint
int	getSize() This method returns the size of the partition (the number of subintervals)
double	getUpperBound() This method returns the upper bound
double	getUpperValue() This method returns the upper midpoint
double	getValue(int i) This method return the midpoint of the interval corresponding to a given index
double	getWidth() This method returns the width of the partition
