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