57 | * A <code>Locale</code> object represents a specific geographical, political, |
58 | * or cultural region. An operation that requires a <code>Locale</code> to perform |
59 | * its task is called <em>locale-sensitive</em> and uses the <code>Locale</code> |
60 | * to tailor information for the user. For example, displaying a number |
61 | * is a locale-sensitive operation--the number should be formatted |
62 | * according to the customs/conventions of the user's native country, |
63 | * region, or culture. |
64 | * |
65 | * The Locale class is not suitable for subclassing. |
66 | * |
67 | * <P> |
68 | * You can create a <code>Locale</code> object using the constructor in |
69 | * this class: |
70 | * \htmlonly<blockquote>\endhtmlonly |
71 | * <pre> |
72 | * Locale( const char* language, |
73 | * const char* country, |
74 | * const char* variant); |
75 | * </pre> |
76 | * \htmlonly</blockquote>\endhtmlonly |
77 | * The first argument to the constructors is a valid <STRONG>ISO |
78 | * Language Code.</STRONG> These codes are the lower-case two-letter |
79 | * codes as defined by ISO-639. |
80 | * You can find a full list of these codes at: |
81 | * <BR><a href ="http://www.loc.gov/standards/iso639-2/"> |
82 | * http://www.loc.gov/standards/iso639-2/</a> |
83 | * |
84 | * <P> |
85 | * The second argument to the constructors is a valid <STRONG>ISO Country |
86 | * Code.</STRONG> These codes are the upper-case two-letter codes |
87 | * as defined by ISO-3166. |
88 | * You can find a full list of these codes at a number of sites, such as: |
89 | * <BR><a href="http://www.iso.org/iso/en/prods-services/iso3166ma/index.html"> |
90 | * http://www.iso.org/iso/en/prods-services/iso3166ma/index.html</a> |
91 | * |
92 | * <P> |
93 | * The third constructor requires a third argument--the <STRONG>Variant.</STRONG> |
94 | * The Variant codes are vendor and browser-specific. |
95 | * For example, use REVISED for a language's revised script orthography, and POSIX for POSIX. |
96 | * Where there are two variants, separate them with an underscore, and |
97 | * put the most important one first. For |
98 | * example, a Traditional Spanish collation might be referenced, with |
99 | * "ES", "ES", "Traditional_POSIX". |
100 | * |
101 | * <P> |
102 | * Because a <code>Locale</code> object is just an identifier for a region, |
103 | * no validity check is performed when you construct a <code>Locale</code>. |
104 | * If you want to see whether particular resources are available for the |
105 | * <code>Locale</code> you construct, you must query those resources. For |
106 | * example, ask the <code>NumberFormat</code> for the locales it supports |
107 | * using its <code>getAvailableLocales</code> method. |
108 | * <BR><STRONG>Note:</STRONG> When you ask for a resource for a particular |
109 | * locale, you get back the best available match, not necessarily |
110 | * precisely what you asked for. For more information, look at |
111 | * <code>ResourceBundle</code>. |
112 | * |
113 | * <P> |
114 | * The <code>Locale</code> class provides a number of convenient constants |
115 | * that you can use to create <code>Locale</code> objects for commonly used |
116 | * locales. For example, the following refers to a <code>Locale</code> object |
117 | * for the United States: |
118 | * \htmlonly<blockquote>\endhtmlonly |
119 | * <pre> |
120 | * Locale::getUS() |
121 | * </pre> |
122 | * \htmlonly</blockquote>\endhtmlonly |
123 | * |
124 | * <P> |
125 | * Once you've created a <code>Locale</code> you can query it for information about |
126 | * itself. Use <code>getCountry</code> to get the ISO Country Code and |
127 | * <code>getLanguage</code> to get the ISO Language Code. You can |
128 | * use <code>getDisplayCountry</code> to get the |
129 | * name of the country suitable for displaying to the user. Similarly, |
130 | * you can use <code>getDisplayLanguage</code> to get the name of |
131 | * the language suitable for displaying to the user. Interestingly, |
132 | * the <code>getDisplayXXX</code> methods are themselves locale-sensitive |
133 | * and have two versions: one that uses the default locale and one |
134 | * that takes a locale as an argument and displays the name or country in |
135 | * a language appropriate to that locale. |
136 | * |
137 | * <P> |
138 | * ICU provides a number of classes that perform locale-sensitive |
139 | * operations. For example, the <code>NumberFormat</code> class formats |
140 | * numbers, currency, or percentages in a locale-sensitive manner. Classes |
141 | * such as <code>NumberFormat</code> have a number of convenience methods |
142 | * for creating a default object of that type. For example, the |
143 | * <code>NumberFormat</code> class provides these three convenience methods |
144 | * for creating a default <code>NumberFormat</code> object: |
145 | * \htmlonly<blockquote>\endhtmlonly |
146 | * <pre> |
147 | * UErrorCode success = U_ZERO_ERROR; |
148 | * Locale myLocale; |
149 | * NumberFormat *nf; |
150 | * |
151 | * nf = NumberFormat::createInstance( success ); delete nf; |
152 | * nf = NumberFormat::createCurrencyInstance( success ); delete nf; |
153 | * nf = NumberFormat::createPercentInstance( success ); delete nf; |
154 | * </pre> |
155 | * \htmlonly</blockquote>\endhtmlonly |
156 | * Each of these methods has two variants; one with an explicit locale |
157 | * and one without; the latter using the default locale. |
158 | * \htmlonly<blockquote>\endhtmlonly |
159 | * <pre> |
160 | * nf = NumberFormat::createInstance( myLocale, success ); delete nf; |
161 | * nf = NumberFormat::createCurrencyInstance( myLocale, success ); delete nf; |
162 | * nf = NumberFormat::createPercentInstance( myLocale, success ); delete nf; |
163 | * </pre> |
164 | * \htmlonly</blockquote>\endhtmlonly |
165 | * A <code>Locale</code> is the mechanism for identifying the kind of object |
166 | * (<code>NumberFormat</code>) that you would like to get. The locale is |
167 | * <STRONG>just</STRONG> a mechanism for identifying objects, |
168 | * <STRONG>not</STRONG> a container for the objects themselves. |
169 | * |
170 | * <P> |
171 | * Each class that performs locale-sensitive operations allows you |
172 | * to get all the available objects of that type. You can sift |
173 | * through these objects by language, country, or variant, |
174 | * and use the display names to present a menu to the user. |
175 | * For example, you can create a menu of all the collation objects |
176 | * suitable for a given language. Such classes implement these |
177 | * three class methods: |
178 | * \htmlonly<blockquote>\endhtmlonly |
179 | * <pre> |
180 | * static Locale* getAvailableLocales(int32_t& numLocales) |
181 | * static UnicodeString& getDisplayName(const Locale& objectLocale, |
182 | * const Locale& displayLocale, |
183 | * UnicodeString& displayName) |
184 | * static UnicodeString& getDisplayName(const Locale& objectLocale, |
185 | * UnicodeString& displayName) |
186 | * </pre> |
187 | * \htmlonly</blockquote>\endhtmlonly |
