All Implemented Interfaces:
Closeable, AutoCloseable
public class CsvWriter extends nz.org.riskscape.engine.output.RiskscapeWriter implements AutoCloseable

Very simple csv writer, to avoid the ceremony and geometry-required-ness of the geotools one. Quotes values with double quotes if they contain a double quote, a comma or a return character.

  • Field Details

    • COLUMN_MAX_CHARACTERS

      public static final int COLUMN_MAX_CHARACTERS

      Per column character limit beyond which column content will be truncated. This is because Excel has a limit of 32,767 characters and will not display a file that contains columns that exceed that limit.

      Ideally this would be configurable, but we have no facility for passing options to output formats (GL#420)
