    • Method Detail

      • size

        int size()
        The number of columns in the Row.
        Returns:
        number of columns
      • get

        String get​(int columnIndex)
        Gets the content of the cell on the basis of its cell position within the Row. Counting is 0-based.
        Parameters:
        columnIndex - the position of the cell within the Row
        Returns:
        the content of the cell
      • get

        String get​(String columnName)
        Gets the content of the cell in the column named columnName. This method depends on the availability of a Header, or will otherwise throw an exception
        Parameters:
        columnName - the cell of the Row in the same column as the header with name columnName
        Returns:
        the content of the cell
      • getColumnName

        String getColumnName​(int columnIndex)
        Gets the column name belonging to the cell. This method depends on the availability of a Header, or will otherwise throw an exception
        Parameters:
        columnIndex - the position of the header cell within the Header line
        Returns:
        the name of the column
      • hasHeader

        boolean hasHeader()
        Returns true if a Header has been set for this Row.
        Returns:
        true if Header has been found
      • getHeader

        Header getHeader()
        Returns the Headers and throws an exception if it does not exist. Use hasHeader() if you want to prevent the throwing of an exception when a Header can lack
        Returns:
        the Header for the Row
      • reportOnEndOfLine

        RowReport reportOnEndOfLine()
        Generates a report on the Row with focus on the end of the row. This is internally used when there is a syntax error in the line. It could also be used when there is an error that can not be traced back to a single cell.
        Returns:
        report on the row with focus on the end of the row
      • reportOnColumn

        RowReport reportOnColumn​(int columnIndex)
        Generates a report on the Row with focus on a particular cell. The report can return lines for web consumption (assisting highlighting) or monospaced font printing with dual lines, the first holding the value of the line, the second showing where the error occurred.
        Parameters:
        columnIndex - the index of the column to focus the report on
        Returns:
        report on the row with focus on a particular cell
