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