fi.pelam.csv.stream

CsvWriter

final class CsvWriter extends AnyRef

Opposite of CsvReader. The API is simple. There are just 3 public methods. One to write a single cell and another to write a TraversableOnce of cells.

The third method goToNextRow should be called last after the last cell to write the line feed at the end of the file.

The cells are expected to be in top to bottom left to right order. The sequence of cells can contain holes. Empty cells in CSV data will be emitted for those.

This class handles quoting, but all other special processing is handled by fi.pelam.csv.cell.Cell.serializedString implementations.

Note

This class does not flush or close the output stream. Client must take care of that.

    Shortcut to call write for each cell in a traversable.

    The cells are expected to be in CellKey order.

    cells

    sequence of cells to be written.

  24. def write(cell: Cell): Unit

    Write a single cell to output stream.

    Write a single cell to output stream.

    Will throw a RuntimeException if cell with succeeding CellKey has already been written. This is because cells are expected to be written in natural order of CellKeys (rows top down, columns right to left).

    cell

    to write.
