org.pentaho.reporting.engine.classic.core.SubReport
A subreport element. A subreport can be attached to a root-level band and will be printed afterwards. Subreports have their own tablemodel (queried with the sub-reports's defined query and the master report's data-factory).
A sub-report that has been added to a root-level band will always be printed below the root-level band.
Sub-reports can have import and export parameters. The parameter mapping can be defined freely, so a subreport is not required to use the same column names as the parent report.
If a global import or export is defined (by adding the parameter mapping "*" => "*") the other defined parameter mappings will be ignored. @author Thomas Morgner
