public Class OrderedHashSet<E>

Class Inheritance

extends HashSet<E>
implements List<E>, Set<E>

All Implemented Interfaces

org.hsqldb.lib.Set, org.hsqldb.lib.Collection, org.hsqldb.lib.List

A list which is also a 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.
