Class ConcurrentLongHashSet

java.lang.Object

org.apache.activemq.artemis.utils.collections.ConcurrentLongHashSet

public class ConcurrentLongHashSet
extends Object

Concurrent hash set for primitive longs Provides similar methods as a ConcurrentSet<Long> but since it's an open hash map with linear probing, no node allocations are required to store the values.

Items MUST be >= 0.
