  java.util.AbstractCollection<E>

All Implemented Interfaces:

Serializable, Cloneable, Iterable<E>, Collection<E>, Set<E>

public class ListableHashSet<E>
extends LinkedHashSet<E>

Set implementation with these properties which make it suitable for use with JiBX:

• Iteration order reflects addition order (this property is inherited from LinkedHashSet)
• An addUnique(E) method that throws JiBXException if the item is already in the set (suitable for use as a JiBX add-method)

Since:

1.0.64
