Examples of org.jfree.report.data.GlobalMasterRow

org.jfree.report.data.GlobalMasterRow
This data row holds all statefull information from the datasources of the report.
When doing subreports, a datarow only has access to its own dataset and the columns from the next direct subreport, which have been marked as exported. @author Thomas Morgner
