Class ConcurrentHashSet<E>

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractSet<E>

org.infinispan.commons.util.concurrent.ConcurrentHashSet<E>

All Implemented Interfaces:

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

@Deprecated
public class ConcurrentHashSet<E>
extends AbstractSet<E>
implements 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
