类 ConcurrentSortedLongPairSet

java.lang.Object

org.apache.pulsar.common.util.collections.ConcurrentSortedLongPairSet

所有已实现的接口:

LongPairSet

public class ConcurrentSortedLongPairSet
extends Object
implements LongPairSet

Sorted concurrent LongPairSet which is not fully accurate in sorting. ConcurrentSortedLongPairSet creates separate ConcurrentLongPairSet for unique first-key of inserted item. So, it can iterate over all items by sorting on item's first key. However, item's second key will not be sorted. eg:

  insert: (1,2), (1,4), (2,1), (1,5), (2,6)
  while iterating set will first read all the entries for items whose first-key=1 and then first-key=2.
  output: (1,4), (1,5), (1,2), (2,6), (2,1)
 

This map can be expensive and not recommended if set has to store large number of unique item.first's key because set has to create that many ConcurrentLongPairSet objects.
