Hi Trejkaz, A normal codec would call visitor.compare on smaller and smaller cells (1D ranges for the 1D case) of the byte[] space and depending on that result would call one of the visit methods, or skip that cell if compare returned CELL_OUTSIDE_QUERY.
I think for your case (to migrate all values) you could simply call visitor.visit(int docID, byte[] packedValue) for every value in the segment.
