Class ConcurrentOpenHashSet<V>

java.lang.Object

org.apache.pulsar.common.util.collections.ConcurrentOpenHashSet<V>

Type Parameters:

V -

public class ConcurrentOpenHashSet<V>
extends java.lang.Object

Concurrent hash set.

Provides similar methods as a ConcurrentMap<K,V> but since it's an open hash map with linear probing, no node allocations are required to store the values.
