Detailed Description

DateFormatSymbols is a public class for encapsulating localizable date-time formatting data -- including timezone data.

DateFormatSymbols is used by DateFormat and SimpleDateFormat.

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.

Constructor & Destructor Documentation

DateFormatSymbols::DateFormatSymbols UErrorCode status  ) 
 

Construct a DateFormatSymbols object by loading format data from resources for the default locale, in the default calendar (Gregorian).

NOTE: This constructor will never fail; if it cannot get resource data for the default locale, it will return a last-resort object based on hard-coded strings.

Parameters:
status Status code. Failure results if the resources for the default cannot be found or cannot be loaded
Stable:
ICU 2.0

DateFormatSymbols::DateFormatSymbols const Locale locale,
UErrorCode status
 

Construct a DateFormatSymbols object by loading format data from resources for the given locale, in the default calendar (Gregorian).

Parameters:

DateFormatSymbols::DateFormatSymbols const char *  type,
UErrorCode status
 

Construct a DateFormatSymbols object by loading format data from resources for the default locale, in the default calendar (Gregorian).

NOTE: This constructor will never fail; if it cannot get resource data for the default locale, it will return a last-resort object based on hard-coded strings.

Parameters:
type Type of calendar (as returned by Calendar::getType). Will be used to access the correct set of strings. (NULL or empty string defaults to "gregorian".)
status Status code. Failure results if the resources for the default cannot be found or cannot be loaded
