      • getValueMap

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

        boolean[] getNullAxisFlags()
        Returns an array of boolean values which identify which axis of the cached segment contained null values.
        Returns:
        An array of boolean values.
