      Map<CellKey,Object> getValueMap()
      Converts contents of this segment into a cellkey/value map. Use only for sparse segments.

      Map containing cell values keyed by their coordinates

    • getValueArray

      Object getValueArray()
      Returns an array of values.

      Use only for dense segments.

      Returns:
      An array of values

    • getNullValueIndicators

      BitSet getNullValueIndicators()
      Returns a bit-set indicating whether values are null. The ordinals in the bit-set correspond to the indexes in the array returned from getValueArray().

      Use only for dense segments of native values.

      Returns:
      Indicators

    • getAxisValueSets

      SortedSet<Comparable>[] getAxisValueSets()
      Returns the cached axis value sets to be used as an initializer for the segment's axis.
      Returns:
      An array of SortedSets which was cached previously.

    • getNullAxisFlags
