org.eclipse.birt.report.model.api.ReportElementHandle
org.eclipse.birt.report.model.api.GroupHandle
Represents both list and table groups in the design. Groups provide a way of showing common headings for a group of related rows.
A group is defined by a group key. The key is a column from the query. If the group key is a time field then user often want to group on an interval such as month or quarter.
