/**
|
|
* 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>
|
|
* \htmlonly</blockquote>\endhtmlonly
