Class GroupList

java.lang.Object
  com.jrefinery.report.GroupList

All Implemented Interfaces:

java.lang.Cloneable, java.io.Serializable

Direct Known Subclasses:

UnmodifiableGroupList

public class GroupList

extends java.lang.Object

implements java.lang.Cloneable, java.io.Serializable

The group list is used to store groups in a ordered way. The less specific groups are guaranteed to be listed before any more specific subgroup.

Groups are ordered by comparing the declared fieldnames for the groups. A subgroup of an group must contain all fields from its parent plus at least one new field.

This implementation is not synchronized.
