org.pentaho.reporting.engine.classic.core.Group
A report group. Reports can contain any number of (nested) groups. The order of the fields is not important. If the group does not contain any fields, the group spans the whole report from the first to the last row (such a group is called the default group).
The group's field list should not be modified after the group was added to the group list, or the results are undefined.
Groups of the same GroupList must have a subgroup relation. The designated child group must contain all fields of the direct parent plus at least one new field. There is no requirement, that the referenced field actually exists, if it doesn't, null is assumed as field value.
It is recommended that the name of the group is unique within the report. The name will not be used internally to identify the group, but most functions depend on a recognizable group name to identify the group to be processed. @author David Gilbert @author Thomas Morgner @see GroupList
