* 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. *
* 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. *
* 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. *
* New DateFormatSymbols sub-classes may be added to support SimpleDateFormat * for date-time formatting for additional locales. */ class U_I18N_API DateFormatSymbols { public: /** * Construct a DateFormatSymbols object by loading format data from * resources for the default locale. *
