An operation that requires a <code>Locale</code> to perform + * its task is called <em>locale-sensitive</em> and uses the <code>Locale</code> + * 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. + * + * <P> + * You can create a <code>Locale</code> object using the constructor in + * this class: + * \htmlonly<blockquote>\endhtmlonly + * <pre> + * Locale( const char* language, + * const char* country, + * const char* variant); + * </pre> + * \htmlonly</blockquote>\endhtmlonly + * The first argument to the constructors is a valid <STRONG>ISO + * Language Code.</STRONG> These codes are the lower-case two-letter + * codes as defined by ISO-639. + * You can find a full list of these codes at: + * <BR><a href ="http://www.loc.gov/standards/iso639-2/"> + * http://www.loc.gov/standards/iso639-2/</a> + * + * <P> + * The second argument to the constructors is a valid <STRONG>ISO Country + * Code.</STRONG> 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: + * <BR><a href="http://www.iso.org/iso/en/prods-services/iso3166ma/index.html"> + * http://www.iso.org/iso/en/prods-services/iso3166ma/index.html</a> + * + * <P> + * The third constructor requires a third argument--the <STRONG>Variant.</STRONG> + * 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". + * + * <P> + * Because a <code>Locale</code> object is just an identifier for a region, + * no validity check is performed when you construct a <code>Locale</code>. + * If you want to see whether particular resources are available for the + * <code>Locale</code> you construct, you must query those resources. For + * example, ask the <code>NumberFormat</code> for the locales it supports + * using its <code>getAvailableLocales</code> method. + * <BR><STRONG>Note:</STRONG> 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 + * <code>ResourceBundle</code>. + * + * <P> + * The <code>Locale</code> class provides a number of convenient constants + * that you can use to create <code>Locale</code> objects for commonly used + * locales. For example, the following refers to a <code>Locale</code> object + * for the United States: + * \htmlonly<blockquote>\endhtmlonly + * <pre> + * Locale::getUS() + * </pre> + * \htmlonly</blockquote>\endhtmlonly + * + * <P> + * Once you've created a <code>Locale</code> you can query it for information about + * itself. Use <code>getCountry</code> to get the ISO Country Code and + * <code>getLanguage</code> to get the ISO Language Code. You can + * use <code>getDisplayCountry</code> to get the + * name of the country suitable for displaying to the user. Similarly, + * you can use <code>getDisplayLanguage</code> to get the name of + * the language suitable for displaying to the user. Interestingly, + * the <code>getDisplayXXX</code> 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. + * + * <P> + * ICU provides a number of classes that perform locale-sensitive + * operations. For example, the <code>NumberFormat</code> class formats + * numbers, currency, or percentages in a locale-sensitive manner. Classes + * such as <code>NumberFormat</code> have a number of convenience methods + * for creating a default object of that type. For example, the + * <code>NumberFormat</code> class provides these three convenience methods + * for creating a default <code>NumberFormat</code> object: + * \htmlonly<blockquote>\endhtmlonly + * <pre> + * 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; + * </pre> + * \htmlonly</blockquote>\endhtmlonly + * Each of these methods has two variants; one with an explicit locale + * and one without; the latter using the default locale. + * \htmlonly<blockquote>\endhtmlonly + * <pre> + * nf = NumberFormat::createInstance( myLocale, success ); delete nf; + * nf = NumberFormat::createCurrencyInstance( myLocale, success ); delete nf; + * nf = NumberFormat::createPercentInstance( myLocale, success ); delete nf; + * </pre> + * \htmlonly</blockquote>\endhtmlonly + * A <code>Locale</code> is the mechanism for identifying the kind of object + * (<code>NumberFormat</code>) that you would like to get. The locale is + * <STRONG>just</STRONG> a mechanism for identifying objects, + * <STRONG>not</STRONG> a container for the objects themselves. + * + * <P> + * 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: + * \htmlonly<blockquote>\endhtmlonly + * <pre> + * 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) + * </pre> + * \htmlonly</blockquote>\endhtmlonly + * + * @stable ICU 2.0 + * @see ResourceBundle + */ +class U_COMMON_API Locale : public UObject { +public: + /** Useful constant for the Root locale. @stable ICU 4.4 */ + static const Locale &U_EXPORT2 getRoot(void); + /** Useful constant for this language. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getEnglish(void); + /** Useful constant for this language. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getFrench(void); + /** Useful constant for this language. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getGerman(void); + /** Useful constant for this language. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getItalian(void); + /** Useful constant for this language. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getJapanese(void); + /** Useful constant for this language. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getKorean(void); + /** Useful constant for this language. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getChinese(void); + /** Useful constant for this language. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getSimplifiedChinese(void); + /** Useful constant for this language. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getTraditionalChinese(void); + + /** Useful constant for this country/region. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getFrance(void); + /** Useful constant for this country/region. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getGermany(void); + /** Useful constant for this country/region. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getItaly(void); + /** Useful constant for this country/region. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getJapan(void); + /** Useful constant for this country/region. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getKorea(void); + /** Useful constant for this country/region. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getChina(void); + /** Useful constant for this country/region. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getPRC(void); + /** Useful constant for this country/region. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getTaiwan(void); + /** Useful constant for this country/region. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getUK(void); + /** Useful constant for this country/region. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getUS(void); + /** Useful constant for this country/region. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getCanada(void); + /** Useful constant for this country/region. @stable ICU 2.0 */ + static const Locale &U_EXPORT2 getCanadaFrench(void); + + + /** + * Construct a default locale object, a Locale for the default locale ID. + * + * @see getDefault + * @see uloc_getDefault + * @stable ICU 2.0 + */ + Locale(); + + /** + * Construct a locale from language, country, variant. + * If an error occurs, then the constructed object will be "bogus" + * (isBogus() will return TRUE). + * + * @param language Lowercase 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")' + * + * @param country Uppercase two-letter ISO-3166 code.
