| /** |
| * A <code>Locale</code> object represents a specific geographical, political, |
| * or cultural region. 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 language'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> |
