Examples of javax.media.jai.util.Range

javax.media.jai.util.Range
A class to represent ranges of values. A range is defined to contain all the values between the minimum and maximum values, where the minimum/maximum value can be considered either included or excluded from the range.
This example creates a range of Integers whose minimum value is 1 and the maximum value is 5. The range is inclusive at both ends:
Range intRange = new Range(Integer.class, new Integer(1), new Integer(5));
A Range can be unbounded at either or both of its ends. An unbounded end is specified by passing null for the value of that end. A Range unbounded at both of its ends represents a range of all possible values for the Class of elements in that Range. The isMinIncluded() method will always return true for a Range unbounded on the minimum side and correspondingly the isMaxIncluded() method will always return true for a Range unbounded on the maximum side.
An empty range is defined as a Range whose minimum value is greater than it's maximum value if the ends are included, or as a Range whose minimum value is greater than or equal to it's maximum value, if the minimum or the maximum value is excluded. @since JAI 1.1
