  43  * DateFormatSymbols is a public class for encapsulating localizable date-time
  44  * formatting data -- including timezone data. DateFormatSymbols is used by
  45  * DateFormat and SimpleDateFormat.
  46  * <P>
  47  * Rather than first creating a DateFormatSymbols to get a date-time formatter
  48  * by using a SimpleDateFormat constructor, clients are encouraged to create a
  49  * date-time formatter using the getTimeInstance(), getDateInstance(), or
  50  * getDateTimeInstance() method in DateFormat. Each of these methods can return a
  51  * date/time formatter initialized with a default format pattern along with the
  52  * date-time formatting data for a given or default locale. After a formatter is
  53  * created, clients may modify the format pattern using the setPattern function
  54  * as so desired. For more information on using these formatter factory
  55  * functions, see DateFormat.
  56  * <P>
  57  * If clients decide to create a date-time formatter with a particular format
  58  * pattern and locale, they can do so with new SimpleDateFormat(aPattern,
  59  * new DateFormatSymbols(aLocale)).  This will load the appropriate date-time
  60  * formatting data from the locale.
  61  * <P>
  62  * DateFormatSymbols objects are clonable. When clients obtain a
  63  * DateFormatSymbols object, they can feel free to modify the date-time
  64  * formatting data as necessary. For instance, clients can
  65  * replace the localized date-time format pattern characters with the ones that
  66  * they feel easy to remember. Or they can change the representative cities
  67  * originally picked by default to using their favorite ones.
  68  * <P>
  69  * DateFormatSymbols are not expected to be subclassed. Data for a calendar is
  70  * loaded out of resource bundles.  The 'type' parameter indicates the type of
  71  * calendar, for example, "gregorian" or "japanese".  If the type is not gregorian
  72  * (or NULL, or an empty string) then the type is appended to the resource name,
  73  * for example,  'Eras_japanese' instead of 'Eras'.   If the resource 'Eras_japanese' did
  74  * not exist (even in root), then this class will fall back to just 'Eras', that is,
  75  * Gregorian data.  Therefore, the calendar implementor MUST ensure that the root
  76  * locale at least contains any resources that are to be particularized for the
  77  * calendar type.
