Locale
represents a specific geographical, political,
michael@0: * or cultural region. An operation that requires a Locale
to perform
michael@0: * its task is called locale-sensitive and uses the Locale
michael@0: * to tailor information for the user. For example, displaying a number
michael@0: * is a locale-sensitive operation--the number should be formatted
michael@0: * according to the customs/conventions of the user's native country,
michael@0: * region, or culture. In the C APIs, a locales is simply a const char string.
michael@0: *
michael@0: *
michael@0: * You create a Locale
with one of the three options listed below.
michael@0: * Each of the component is separated by '_' in the locale string.
michael@0: * \htmlonly
\endhtmlonly michael@0: *\endhtmlonly michael@0: * The first option is a valid ISO michael@0: * Language Code. These codes are the lower-case two-letter michael@0: * codes as defined by ISO-639. michael@0: * You can find a full list of these codes at a number of sites, such as: michael@0: *michael@0: * \code michael@0: * newLanguage michael@0: * michael@0: * newLanguage + newCountry michael@0: * michael@0: * newLanguage + newCountry + newVariant michael@0: * \endcode michael@0: *michael@0: * \htmlonly
michael@0: * The second option includes an additonal ISO Country
michael@0: * Code. These codes are the upper-case two-letter codes
michael@0: * as defined by ISO-3166.
michael@0: * You can find a full list of these codes at a number of sites, such as:
michael@0: *
michael@0: * http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html
michael@0: *
michael@0: *
michael@0: * The third option requires another additonal information--the michael@0: * Variant. michael@0: * The Variant codes are vendor and browser-specific. michael@0: * For example, use WIN for Windows, MAC for Macintosh, and POSIX for POSIX. michael@0: * Where there are two variants, separate them with an underscore, and michael@0: * put the most important one first. For michael@0: * example, a Traditional Spanish collation might be referenced, with michael@0: * "ES", "ES", "Traditional_WIN". michael@0: * michael@0: *
michael@0: * Because a Locale
is just an identifier for a region,
michael@0: * no validity check is performed when you specify a Locale
.
michael@0: * If you want to see whether particular resources are available for the
michael@0: * Locale
you asked for, you must query those resources. For
michael@0: * example, ask the UNumberFormat
for the locales it supports
michael@0: * using its getAvailable
method.
michael@0: *
Note: When you ask for a resource for a particular
michael@0: * locale, you get back the best available match, not necessarily
michael@0: * precisely what you asked for. For more information, look at
michael@0: * UResourceBundle
.
michael@0: *
michael@0: *
michael@0: * The Locale
provides a number of convenient constants
michael@0: * that you can use to specify the commonly used
michael@0: * locales. For example, the following refers to a locale
michael@0: * for the United States:
michael@0: * \htmlonly
\endhtmlonly michael@0: *\endhtmlonly michael@0: * michael@0: *michael@0: * \code michael@0: * ULOC_US michael@0: * \endcode michael@0: *michael@0: * \htmlonly
michael@0: * Once you've specified a locale you can query it for information about
michael@0: * itself. Use uloc_getCountry
to get the ISO Country Code and
michael@0: * uloc_getLanguage
to get the ISO Language Code. You can
michael@0: * use uloc_getDisplayCountry
to get the
michael@0: * name of the country suitable for displaying to the user. Similarly,
michael@0: * you can use uloc_getDisplayLanguage
to get the name of
michael@0: * the language suitable for displaying to the user. Interestingly,
michael@0: * the uloc_getDisplayXXX
methods are themselves locale-sensitive
michael@0: * and have two versions: one that uses the default locale and one
michael@0: * that takes a locale as an argument and displays the name or country in
michael@0: * a language appropriate to that locale.
michael@0: *
michael@0: *
michael@0: * The ICU provides a number of services that perform locale-sensitive
michael@0: * operations. For example, the unum_xxx
functions format
michael@0: * numbers, currency, or percentages in a locale-sensitive manner.
michael@0: *
\endhtmlonly michael@0: *\endhtmlonly michael@0: * Each of these methods has two variants; one with an explicit locale michael@0: * and one without; the latter using the default locale. michael@0: * \htmlonlymichael@0: * \code michael@0: * UErrorCode success = U_ZERO_ERROR; michael@0: * UNumberFormat *nf; michael@0: * const char* myLocale = "fr_FR"; michael@0: * michael@0: * nf = unum_open( UNUM_DEFAULT, NULL, success ); michael@0: * unum_close(nf); michael@0: * nf = unum_open( UNUM_CURRENCY, NULL, success ); michael@0: * unum_close(nf); michael@0: * nf = unum_open( UNUM_PERCENT, NULL, success ); michael@0: * unum_close(nf); michael@0: * \endcode michael@0: *michael@0: * \htmlonly
\endhtmlonly michael@0: *\endhtmlonly michael@0: * Amichael@0: * \code michael@0: * michael@0: * nf = unum_open( UNUM_DEFAULT, myLocale, success ); michael@0: * unum_close(nf); michael@0: * nf = unum_open( UNUM_CURRENCY, myLocale, success ); michael@0: * unum_close(nf); michael@0: * nf = unum_open( UNUM_PERCENT, myLocale, success ); michael@0: * unum_close(nf); michael@0: * \endcode michael@0: *michael@0: * \htmlonly
Locale
is the mechanism for identifying the kind of services
michael@0: * (UNumberFormat
) that you would like to get. The locale is
michael@0: * just a mechanism for identifying these services.
michael@0: *
michael@0: * michael@0: * Each international serivce that performs locale-sensitive operations michael@0: * allows you michael@0: * to get all the available objects of that type. You can sift michael@0: * through these objects by language, country, or variant, michael@0: * and use the display names to present a menu to the user. michael@0: * For example, you can create a menu of all the collation objects michael@0: * suitable for a given language. Such classes implement these michael@0: * three class methods: michael@0: * \htmlonly
\endhtmlonly michael@0: *\endhtmlonly michael@0: *michael@0: * \code michael@0: * const char* uloc_getAvailable(int32_t index); michael@0: * int32_t uloc_countAvailable(); michael@0: * int32_t michael@0: * uloc_getDisplayName(const char* localeID, michael@0: * const char* inLocaleID, michael@0: * UChar* result, michael@0: * int32_t maxResultSize, michael@0: * UErrorCode* err); michael@0: * michael@0: * \endcode michael@0: *michael@0: * \htmlonly
michael@0: * Concerning POSIX/RFC1766 Locale IDs, michael@0: * the getLanguage/getCountry/getVariant/getName functions do understand michael@0: * the POSIX type form of language_COUNTRY.ENCODING\@VARIANT michael@0: * and if there is not an ICU-stype variant, uloc_getVariant() for example michael@0: * will return the one listed after the \@at sign. As well, the hyphen michael@0: * "-" is recognized as a country/variant separator similarly to RFC1766. michael@0: * So for example, "en-us" will be interpreted as en_US. michael@0: * As a result, uloc_getName() is far from a no-op, and will have the michael@0: * effect of converting POSIX/RFC1766 IDs into ICU form, although it does michael@0: * NOT map any of the actual codes (i.e. russian->ru) in any way. michael@0: * Applications should call uloc_getName() at the point where a locale ID michael@0: * is coming from an external source (user entry, OS, web browser) michael@0: * and pass the resulting string to other ICU functions. For example, michael@0: * don't use de-de\@EURO as an argument to resourcebundle. michael@0: * michael@0: * @see UResourceBundle michael@0: */ michael@0: michael@0: /** Useful constant for this
