 * DateParser is the "missing" interface for the parsing methods of
 * {@link java.text.DateFormat}. You can obtain an object implementing this
 * interface by using one of the FastDateFormat factory methods.
 * <p>
 * Warning: Since binary compatible methods may be added to this interface in any
 * release, developers are not expected to implement this interface.

     * Equivalent to DateFormat.parse(String).

     * Parse a formatted date string according to the format.  Updates the Calendar with parsed fields.
     * Upon success, the ParsePosition index is updated to indicate how much of the source text was consumed.
     * Not all source text needs to be consumed.  Upon parse failure, ParsePosition error index is updated to
     * the offset of the source text which does not match the supplied format.
     * @param source The text to parse.
     * @param pos On input, the position in the source to start parsing, on output, updated position.
     * @param calendar The calendar into which to set parsed fields.

     * @throws IllegalArgumentException when Calendar has been set to be not lenient, and a parsed field is
     * out of range.
