Examples of JRCrosstabBucket

net.sf.jasperreports.crosstabs.JRCrosstabBucket
Crosstab groups bucketing information interface.
The bucketing informartion consists of the grouping expression and sorting information. The buckets can be sorted according to the natural sorting (if the values implement {@link java.lang.Comparable Comparable}) or using a comparator. @author Lucian Chirita (lucianc@users.sourceforge.net) @version $Id: JRCrosstabBucket.java 3500 2010-03-03 15:56:41Z teodord $
