Detailed Description

A Locale object represents a specific geographical, political, or cultural region.

An operation that requires a Locale to perform its task is called locale-sensitive and uses the Locale to tailor information for the user. For example, displaying a number is a locale-sensitive operation–the number should be formatted according to the customs/conventions of the user's native country, region, or culture.

The Locale class is not suitable for subclassing.

You can create a Locale object using the constructor in this class:

      Locale( const   char*  language,
              const   char*  country,
              const   char*  variant);
The first argument to the constructors is a valid ISO Language Code. These codes are the lower-case two-letter codes as defined by ISO-639. You can find a full list of these codes at:
http://www.loc.gov/standards/iso639-2/

The second argument to the constructors is a valid ISO Country Code. These codes are the upper-case two-letter codes as defined by ISO-3166. You can find a full list of these codes at a number of sites, such as:
http://www.iso.org/iso/en/prods-services/iso3166ma/index.html

The third constructor requires a third argument–the Variant. The Variant codes are vendor and browser-specific. For example, use REVISED for a langauge's revised script orthography, and POSIX for POSIX. Where there are two variants, separate them with an underscore, and put the most important one first. For example, a Traditional Spanish collation might be referenced, with "ES", "ES", "Traditional_POSIX".

Because a Locale object is just an identifier for a region, no validity check is performed when you construct a Locale. If you want to see whether particular resources are available for the Locale you construct, you must query those resources. For example, ask the NumberFormat for the locales it supports using its getAvailableLocales method.
Note: When you ask for a resource for a particular locale, you get back the best available match, not necessarily precisely what you asked for. For more information, look at ResourceBundle.

The Locale class provides a number of convenient constants that you can use to create Locale objects for commonly used locales. For example, the following refers to a Locale object for the United States:

      Locale::getUS()

Once you've created a Locale you can query it for information about itself. Use getCountry to get the ISO Country Code and getLanguage to get the ISO Language Code. You can use getDisplayCountry to get the name of the country suitable for displaying to the user. Similarly, you can use getDisplayLanguage to get the name of the language suitable for displaying to the user. Interestingly, the getDisplayXXX methods are themselves locale-sensitive and have two versions: one that uses the default locale and one that takes a locale as an argument and displays the name or country in a language appropriate to that locale.

ICU provides a number of classes that perform locale-sensitive operations. For example, the NumberFormat class formats numbers, currency, or percentages in a locale-sensitive manner. Classes such as NumberFormat have a number of convenience methods for creating a default object of that type. For example, the NumberFormat class provides these three convenience methods for creating a default NumberFormat object:

    UErrorCode success = U_ZERO_ERROR;
    Locale myLocale;
    NumberFormat *nf;
    nf = NumberFormat::createInstance( success );          delete nf;
    nf = NumberFormat::createCurrencyInstance( success );  delete nf;
    nf = NumberFormat::createPercentInstance( success );   delete nf;
Each of these methods has two variants; one with an explicit locale and one without; the latter using the default locale.
    nf = NumberFormat::createInstance( myLocale, success );          delete nf;
    nf = NumberFormat::createCurrencyInstance( myLocale, success );  delete nf;
    nf = NumberFormat::createPercentInstance( myLocale, success );   delete nf;
A Locale is the mechanism for identifying the kind of object (NumberFormat) that you would like to get. The locale is just a mechanism for identifying objects, not a container for the objects themselves.

Each class that performs locale-sensitive operations allows you to get all the available objects of that type. You can sift through these objects by language, country, or variant, and use the display names to present a menu to the user. For example, you can create a menu of all the collation objects suitable for a given language. Such classes implement these three class methods:

      static Locale* getAvailableLocales(int32_t& numLocales)
      static UnicodeString& getDisplayName(const Locale&  objectLocale,
                                           const Locale&  displayLocale,
                                           UnicodeString& displayName)
      static UnicodeString& getDisplayName(const Locale&  objectLocale,
                                           UnicodeString& displayName)

Constructor & Destructor Documentation

icu::Locale::Locale ( )

Construct a default locale object, a Locale for the default locale ID.

Stable:
ICU 2.0
icu::Locale::Locale ( const char *  language,
const char *  country = 0,
const char *  variant = 0,
const char *  keywordsAndValues = 0 
)

Construct a locale from language, country, variant.

If an error occurs, then the constructed object will be "bogus" (isBogus() will return TRUE).

Parameters
languageLowercase two-letter or three-letter ISO-639 code. This parameter can instead be an ICU style C locale (e.g. "en_US"), but the other parameters must not be used. This parameter can be NULL; if so, the locale is initialized to match the current default locale. (This is the same as using the default constructor.) Please note: The Java Locale class does NOT accept the form 'new Locale("en_US")' but only 'new Locale("en","US")'
countryUppercase two-letter ISO-3166 code. (optional)
variantUppercase vendor and browser specific code. See class description. (optional)
keywordsAndValuesA string consisting of keyword/values pairs, such as "collation=phonebook;currency=euro"

More advanced programs will allow users to use different locales for different fields, e.g. in a spreadsheet.
