java.util.AbstractSet

com.sun.identity.shared.datastruct.OrderedSet

All Implemented Interfaces:

Serializable, Iterable, Collection, Set

public class OrderedSet
extends AbstractSet
implements Set, Serializable

This class extends from AbstractSet. It uses List for storing data so that data is stored in the order input. It overwrites add, iterator and size methods. All other methods it needs are in the base class.
