Class CSVRecord

java.lang.Object
nl.colorize.util.stats.CSVRecord
public class CSVRecord extends Object
One of the records witin a CSV file. Records are usually parsed from a CSV file using CSVFormat, but can also be created programmatically. Fields within the record can be retrieved by index or by column name. The latter is only available if the CSV contains column information.

Note: This class is intended for basic CSV support. When working with CSV files produced by other applications, prefer using the FastCSV library.

  • Constructor Details

    • CSVRecord

      protected CSVRecord(List<String> columns, List<String> cells, CSVFormat format)
      Creates a new CSV record from the specified cells. The column information is optional: null indicates that no column information is available, meaning that cells can only be retrieved by index.

      CSVRecord instances are normally by obtained by parsing CSV files using CSVFormat. There is normally no need for applications to use this constructor directly.
