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.
