Description

IEP-74 declares the following API for the SortedIndexStorage#range method:

    /** Exclude lower bound. */
    byte GREATER = 0;
 
    /** Include lower bound. */
    byte GREATER_OR_EQUAL = 1;
 
    /** Exclude upper bound. */
    byte LESS = 0;
 
    /** Include upper bound. */
    byte LESS_OR_EQUAL = 1 << 1;

    /**
     * Return rows between lower and upper bounds.
     * Fill results rows by fields specified at the projection set.
     *
     * @param low Lower bound of the scan.
     * @param up Lower bound of the scan.
     * @param scanBoundMask Scan bound mask (specify how to work with rows equals to the bounds: include or exclude).
     * @param proj Set of the columns IDs to fill results rows.
     */
    Cursor<Row> scan(Row low, Row up, byte scanBoundMask, BitSet proj);

The scanBoundMask flags are currently not implemented. This API should be revised and implemented, if needed.
