                                             StringWritable... values)
                                      throws java.lang.IllegalArgumentException
        Write a sequence of StringWritableCsvs to a StringBuffer. Null StringWritables are not printed, but separator is still used. Separator is a comma (',')
        Parameters:
        sb - The sb to write to
        values - Zero or more attribute-value pairs to write
        Returns:
        The same sb, with data filled in (if any)
        Throws:
        java.lang.IllegalArgumentException - If sb is null

                                    throws java.lang.IllegalArgumentException
        Parse a String with a StringWritableCsv into its composing Strings represented as Strings. No validation is performed on the individual attribute-values returned.
        Parameters:
        value - The String with the set of attribute-values
        n - Number of entries to return (entries will be null of there were not enough). 0 means unlimited
        offset - How many entries to skip before start returning
        Returns:
        An array of Strings which represent the individual attribute-values
        Throws:
        java.lang.IllegalArgumentException - If value is null or either n or offset are negative

      • parseFrom

        public static java.lang.String[] parseFrom​(java.lang.String value,
                                           int n)
                                    throws java.lang.IllegalArgumentException
        Parse a String with a StringWritableCsv into its composing Strings represented as Strings. No validation is performed on the individual attribute-values returned. Elements are returned starting from the first available attribute-value.
        Parameters:
        value - The String with the set of attribute-values
        n - Number of entries to return (entries will be null of there were not enough). 0 means unlimited
        Returns:
        An array of Strings which represent the individual attribute-values
        Throws:
        java.lang.IllegalArgumentException - If value is null or n is negative
