      • getFilePositionForRow

        public Pair getFilePositionForRow​(int row)
        Returns the start/end byte positions within the input file for the given row. To do this we have to loop over all chunks in the ChunkModel and count the number of lines in each chunk until we get to the line (row) we're looking for. We then grab the correct value from the byteMap for that chunk line, which is the starting byte for it.
        Parameters:
        row -
        Returns:
        the byte position in the file this row corresponds to

      • getRowForBytePos

        public int getRowForBytePos​(long selectedByte)
        Searches the visible chunks to see if any of them contain the given byte. If so, returns the row in the table where it resides. Returns -1 otherwise.
        Parameters:
        selectedByte -
        Returns:
