      pos - input/output parsing parameter.
      Returns:
      the first non-whitespace character.
    • parseNumber

      public static Number parseNumber(String source, NumberFormat format, ParsePosition pos)
      Parses source for a number. This method can parse normal, numeric values as well as special values. These special values include Double.NaN, Double.POSITIVE_INFINITY, Double.NEGATIVE_INFINITY.
      Parameters:
      source - the string to parse
      format - the number format used to parse normal, numeric values.
      pos - input/output parsing parameter.
      Returns:
      the parsed number.
    • parseFixedstring

      public static boolean parseFixedstring(String source, String expected, ParsePosition pos)
      Parse source for an expected fixed string.
      Parameters:
      source - the string to parse
      expected - expected string
      pos - input/output parsing parameter.

    • formatDouble

      public static StringBuffer formatDouble(double value, NumberFormat format, StringBuffer toAppendTo, FieldPosition pos)
      Formats a double value to produce a string. In general, the value is formatted using the formatting rules of format. There are three exceptions to this:
      1. NaN is formatted as '(NaN)'
      2. Positive infinity is formatted as '(Infinity)'
      3. Negative infinity is formatted as '(-Infinity)'
      Parameters:
      value - the double to format.
      format - the format used.
      toAppendTo - where the text is to be appended
      pos - On input: an alignment field, if desired. On output: the offsets of the alignment field
      Returns:
      the value passed in as toAppendTo.
