Class ChineseDateFormat

public class ChineseDateFormat
extends SimpleDateFormat
A concrete DateFormat for ChineseCalendar. This class handles a ChineseCalendar-specific field, ChineseCalendar.IS_LEAP_MONTH. It also redefines the handling of two fields, ERA and YEAR. The former is displayed numerically, instead of symbolically, since it is the numeric cycle number in ChineseCalendar. The latter is numeric, as before, but has no special 2-digit Y2K behavior.

With regard to ChineseCalendar.IS_LEAP_MONTH, this class handles parsing specially. If no string symbol is found at all, this is taken as equivalent to an IS_LEAP_MONTH value of zero. This allows formats to display a special string (e.g., "*") for leap months, but no string for normal months.

Summary of field changes vs. SimpleDateFormat:

 Symbol   Meaning                 Presentation        Example
 ------   -------                 ------------        -------
 G        cycle                   (Number)            78
 y        year of cycle (1..60)   (Number)            17
 l        is leap month           (Text)              4637
