Examples of JRDataset

net.sf.jasperreports.engine.JRDataset
Interface representing a data set that can be used in a report.
A data set consists of parameters, fields, variables, groups and an optional query. When a data set gets instantiated, parameter values and a data source is passed to it.
A report has one main data set and multiple sub data sets that can be instantiated by charts and crosstabs. @author Lucian Chirita (lucianc@users.sourceforge.net) @version $Id: JRDataset.java 3507 2010-03-04 15:02:09Z teodord $ @see net.sf.jasperreports.engine.JRDatasetRun @see net.sf.jasperreports.engine.JRReport#getMainDataset() @see net.sf.jasperreports.engine.JRReport#getDatasets()
