类 ConcurrentLongLongPairHashMap

java.lang.Object

org.apache.pulsar.common.util.collections.ConcurrentLongLongPairHashMap

public class ConcurrentLongLongPairHashMap
extends Object

Concurrent hash map where both keys and values are composed of pairs of longs.

(long,long) --> (long,long)

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 keys and values, and no boxing is required.

Keys MUST be >= 0.
