Class ConcurrentHashSet<E>

java.lang.Object
  extended by edu.stanford.nlp.util.ConcurrentHashSet<E>
All Implemented Interfaces:
Serializable, Iterable<E>, Collection<E>, Set<E>

public class ConcurrentHashSet<E>
extends Object
implements Set<E>, Serializable

A thin wrapper on a ConcurrentHashMap, turning it into a ConcurrentHashSet. Such a thing already exists in Java 1.6, using code such as
Collections.newSetFromMap(new ConcurrentHashMap<Object,Boolean>())
However, this isn't available in Java 1.5, so we do it ourselves.
