    • addOpenClosed

      void addOpenClosed(long lowerKey, long lowerValue, long upperKey, long upperValue)
      Adds the specified range (range that contains all values strictly greater than lower and less than or equal to upper.) 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). 
      
 @param lowerKey :  value for key of lowerEndpoint of Range
 @param lowerValue: value for value of lowerEndpoint of Range
 @param upperKey  : value for key of upperEndpoint of Range
 @param upperValue: value for value of upperEndpoint of Range

    • contains

      boolean contains(long key, long value)
      Determines whether any of this range set's member ranges contains value.

    • rangeContaining

      com.google.common.collect.Range<T> rangeContaining(long key, long value)

    • forEach

      void forEach(LongPairRangeSet.RangeProcessor<T> action)
      Performs the given action for each entry in this map until all entries have been processed or action returns "false". Unless otherwise specified by the implementing class, actions are performed in the order of entry set iteration (if an iteration order is specified.)
