CreateGroupAnchorsFunction
public class CreateGroupAnchorsFunction extends AbstractFunction (Code)
Creates anchor objects for the current group. The anchors generated consist of the group's name and the current group count.

To use the CreateGroupAnchorsFunction set the group's name as the function's group-property value. Next, add a AnchorElement to where the anchor should be generated (usually either the group-header or footer) and give the function's name as fieldname in the anchor-field.
