org.hsqldb.lib.OrderedHashSet
Implementation of an ordered Set which maintains the inserted order of elements and allows access by index. Iterators return the elements in the index order. This class does not store null elements. @author Fred Toussi (fredt@users dot sourceforge.net) @version 1.9.0 @since 1.9.0
