* 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. *
* DateFormatSymbols are not expected to be subclassed. Data for a calendar is * loaded out of resource bundles. The 'type' parameter indicates the type of * calendar, for example, "gregorian" or "japanese". If the type is not gregorian * (or NULL, or an empty string) then the type is appended to the resource name, * for example, 'Eras_japanese' instead of 'Eras'. If the resource 'Eras_japanese' did * not exist (even in root), then this class will fall back to just 'Eras', that is, * Gregorian data. Therefore, the calendar implementor MUST ensure that the root * locale at least contains any resources that are to be particularized for the * calendar type. */ class U_I18N_API DateFormatSymbols : public UObject { public: /** * Construct a DateFormatSymbols object by loading format data from * resources for the default locale, in the default calendar (Gregorian). *
