| SortedGroupIterator | | public class SortedGroupIterator extends SortedIterator implements GroupIterator(Code) | | A SortedGroupIterator is a modified SortedIterator. It sorts a sequence of groups,
and is itself a GroupIterator. The modifications retain extra information about
the items being sorted. The items are each the leading item of a group, and as well
as the item itself, the iterator preserves information about the group: specifically,
an iterator over the items in the group, and the value of the grouping key (if any).
