        // First copy all ways from the first partial block
        copyPartial(ways.getStart(), EntityType.Way, blockWriterWays);
    }
    // Then copy all blocks that contain only ways block-wise
    for (int i = firstWayOnlyBlock; i <= lastWayOnlyBlock; i++) {

        blockWriterWays.write(Constants.BLOCK_TYPE_DATA, null, blob);
    }
    // If the last block contains data other than ways, continue
    if (!lastWayBlockMixed) {

    }
    // But not if we copied the partial block in the beginning already
    if (ways.getStart() == ways.getEnd()) {
        return;
    }
    // Copy the remaining ways group-wise
