Class SegmentCollection

    • Field Detail

      • segments

        protected final java.util.NavigableMap<java.lang.Double,​SegmentWithRange> segments
        Maps the upper end of a range to the corresponding segment. The range in the value is the range of keyspace the segment has been assigned. The range in the value is NOT the same as the difference between two keys. The keys correspond to the range that the client should route to, where as the one in the value is the range the segment it assigned. These may be different if a client still has a preceding segment in its map. In which case a segment's keys may not contain the full assigned range.
