Class ConcurrentHashSet<E>

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Iterable<E>, java.util.Collection<E>, java.util.Set<E>
    @Deprecated
public class ConcurrentHashSet<E>
extends java.util.AbstractSet<E>
implements java.io.Serializable
    Deprecated.
    since 10.0, use ConcurrentHashMap.newKeySet() instead.
    A simple Set implementation backed by a ConcurrentHashMap 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:
    4.0
