    Method
    Description
    void
    write(Map<String,?> values, String... nameMapping)
    Writes the values of the Map as columns of a CSV file, using the supplied name mapping to map values to the appropriate columns.

    • write

      void write(Map<String,?> values, String... nameMapping) throws IOException
      Writes the values of the Map as columns of a CSV file, using the supplied name mapping to map values to the appropriate columns. toString() will be called on each element prior to writing.
      Parameters:
      values - the Map containing the values to write
      nameMapping - an array of Strings linking the Map keys to their corresponding CSV columns (the array length should match the number of columns). A null entry in the array indicates that the column should be ignored (the column will be empty).
      Throws:
      IOException - if an I/O error occurred
      NullPointerException - if values or nameMapping are null
      SuperCsvException - if there was a general exception while writing

    • write

      void write(Map<String,?> values, String[] nameMapping, CellProcessor[] processors) throws IOException
      Writes the values of the Map as columns of a CSV file, using the supplied name mapping to map values to the appropriate columns. toString() will be called on each element prior to writing.
      Parameters:
      values - the Map containing the values to write
      nameMapping - an array of Strings linking the Map keys to their corresponding CSV columns (the array length should match the number of columns). A null entry in the array indicates that the column should be ignored (the column will be empty).
      processors - an array of CellProcessors used to further process data before it is written (each element in the processors array corresponds with a CSV column - the number of processors should match the number of columns). A null entry indicates no further processing is required (the value returned by toString() will be written as the column value).
      Throws:
      IOException - if an I/O error occurred
      NullPointerException - if values or nameMapping are null
      SuperCsvConstraintViolationException - if a CellProcessor constraint failed
      SuperCsvException - if there was a general exception while writing
