@Deprecated public class ConcurrentHashSet<E> extends AbstractSet<E> implements Serializable
Deprecated.since 10.0, useConcurrentHashMap.newKeySet()
instead.A simple Set implementation backed by aConcurrentHashMap
to deal with the fact that the JDK does not have a proper concurrent Set implementation that uses efficient lock striping. Note that values are stored as keys in the underlying Map, with a static dummy object as value.- Since:
