Class ConcurrentOpenLongPairRangeSet<T extends Comparable<T>>

java.lang.Object
org.apache.pulsar.common.util.collections.ConcurrentOpenLongPairRangeSet<T>
All Implemented Interfaces:
LongPairRangeSet<T>
public class ConcurrentOpenLongPairRangeSet<T extends Comparable<T>> extends Object implements LongPairRangeSet<T>
A Concurrent set comprising zero or more ranges of type LongPairRangeSet.LongPair. This can be alternative of RangeSet and can be used if range type is LongPairRangeSet.LongPair 
 Usage:
 a. This can be used if one doesn't want to create object for every new inserted range
 b. It creates BitSet for every unique first-key of the range.
 So, this rangeSet is not suitable for large number of unique keys.

    • addOpenClosed

      public void addOpenClosed(long lowerKey, long lowerValueOpen, long upperKey, long upperValue)
      Adds the specified range to this RangeSet (optional operation). That is, for equal range sets a and b, the result of a.add(range) is that a will be the minimal range set for which both a.enclosesAll(b) and a.encloses(range).

      Note that range will merge given range with any ranges in the range set that are connected with it. Moreover, if range is empty, this is a no-op.

    • contains

      public boolean contains(long key, long value)
      Description copied from interface: LongPairRangeSet

      Description copied from interface: LongPairRangeSet
