  15. def skipRow(row: InternalRow, index: Int): Boolean

    Applies all filters that refer to row fields at the positions from 0 to index.

    Applies all filters that refer to row fields at the positions from 0 to index.

    row

    The internal row to check.

    index

    Maximum field index. The function assumes that all fields from 0 to index position are set.

    returns

    false iff row fields at the position from 0 to index pass filters or there are no applicable filters otherwise false if at least one of the filters returns false.
