/**
|
|
* DateFormatSymbols is a public class for encapsulating localizable date-time
|
|
* formatting data -- including timezone data. DateFormatSymbols is used by
|
|
* DateFormat and SimpleDateFormat.
|
|
* <P>
|
|
* 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.
|
|
* <P>
|
|
* 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.
|
|
* <P>
|
|
* 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.
|
|
* <P>
|
|
* 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.
