| /** |
| * DateFormatSymbols is a public class for encapsulating localizable date-time |
| * formatting data -- including timezone data. DateFormatSymbols is used by |
| * DateFormat and SimpleDateFormat. |
| * <P> |
| * Rather than first creating a DateFormatSymbols to get a date-time formatter |
| * by using a SimpleDateFormat constructor, clients are encouraged to create a |
| * date-time formatter using the getTimeInstance(), getDateInstance(), or |
| * getDateTimeInstance() method in DateFormat. Each of these methods can return a |
| * date/time formatter initialized with a default format pattern along with the |
| * date-time formatting data for a given or default locale. After a formatter is |
| * created, clients may modify the format pattern using the setPattern function |
| * as so desired. For more information on using these formatter factory |
| * functions, see DateFormat. |
| * <P> |
| * If clients decide to create a date-time formatter with a particular format |
| * pattern and locale, they can do so with new SimpleDateFormat(aPattern, |
| * new DateFormatSymbols(aLocale)). This will load the appropriate date-time |
| * formatting data from the locale. |
| * <P> |
| * DateFormatSymbols objects are clonable. When clients obtain a |
| * DateFormatSymbols object, they can feel free to modify the date-time |
| * formatting data as necessary. For instance, clients can |
| * replace the localized date-time format pattern characters with the ones that |
| * they feel easy to remember. Or they can change the representative cities |
| * originally picked by default to using their favorite ones. |
| * <P> |
| * New DateFormatSymbols sub-classes may be added to support SimpleDateFormat |
| * for date-time formatting for additional locales. |
