42 */ | |
43 | |
44 /** | |
45 * A <code>Locale</code> object represents a specific geographical, political, | |
46 * or cultural region. An operation that requires a <code>Locale</code> to perfo
rm | |
47 * its task is called <em>locale-sensitive</em> and uses the <code>Locale</code> | |
48 * to tailor information for the user. For example, displaying a number | |
49 * is a locale-sensitive operation--the number should be formatted | |
50 * according to the customs/conventions of the user's native country, | |
51 * region, or culture. | |
52 * | |
53 * The Locale class is not suitable for subclassing. | |
54 * | |
55 * <P> | |
56 * You can create a <code>Locale</code> object using the constructor in | |
57 * this class: | |
58 * \htmlonly<blockquote>\endhtmlonly | |
59 * <pre> | |
60 * Locale( const char* language, | |
61 * const char* country, | |
62 * const char* variant); | |
63 * </pre> | |
64 * \htmlonly</blockquote>\endhtmlonly | |
65 * The first argument to the constructors is a valid <STRONG>ISO | |
66 * Language Code.</STRONG> These codes are the lower-case two-letter | |
67 * codes as defined by ISO-639. | |
68 * You can find a full list of these codes at: | |
69 * <BR><a href ="http://www.loc.gov/standards/iso639-2/"> | |
70 * http://www.loc.gov/standards/iso639-2/</a> | |
71 * | |
72 * <P> | |
73 * The second argument to the constructors is a valid <STRONG>ISO Country | |
74 * Code.</STRONG> These codes are the upper-case two-letter codes | |
75 * as defined by ISO-3166. | |
76 * You can find a full list of these codes at a number of sites, such as: | |
77 * <BR><a href="http://www.iso.org/iso/en/prods-services/iso3166ma/index.html"> | |
78 * http://www.iso.org/iso/en/prods-services/iso3166ma/index.html</a> | |
79 * | |
80 * <P> | |
81 * The third constructor requires a third argument--the <STRONG>Variant.</STRONG
> | |
82 * The Variant codes are vendor and browser-specific. | |
83 * For example, use REVISED for a langauge's revised script orthography, and POS
IX for POSIX. | |
84 * Where there are two variants, separate them with an underscore, and | |
85 * put the most important one first. For | |
86 * example, a Traditional Spanish collation might be referenced, with | |
87 * "ES", "ES", "Traditional_POSIX". | |
88 * | |
89 * <P> | |
90 * Because a <code>Locale</code> object is just an identifier for a region, | |
91 * no validity check is performed when you construct a <code>Locale</code>. | |
92 * If you want to see whether particular resources are available for the | |
93 * <code>Locale</code> you construct, you must query those resources. For | |
94 * example, ask the <code>NumberFormat</code> for the locales it supports | |
95 * using its <code>getAvailableLocales</code> method. | |
96 * <BR><STRONG>Note:</STRONG> When you ask for a resource for a particular | |
97 * locale, you get back the best available match, not necessarily | |
98 * precisely what you asked for. For more information, look at | |
99 * <code>ResourceBundle</code>. | |
100 * | |
101 * <P> | |
102 * The <code>Locale</code> class provides a number of convenient constants | |
103 * that you can use to create <code>Locale</code> objects for commonly used | |
104 * locales. For example, the following refers to a <code>Locale</code> object | |
105 * for the United States: | |
106 * \htmlonly<blockquote>\endhtmlonly | |
107 * <pre> | |
108 * Locale::getUS() | |
109 * </pre> | |
110 * \htmlonly</blockquote>\endhtmlonly | |
111 * | |
112 * <P> | |
113 * Once you've created a <code>Locale</code> you can query it for information ab
out | |
114 * itself. Use <code>getCountry</code> to get the ISO Country Code and | |
115 * <code>getLanguage</code> to get the ISO Language Code. You can | |
116 * use <code>getDisplayCountry</code> to get the | |
117 * name of the country suitable for displaying to the user. Similarly, | |
118 * you can use <code>getDisplayLanguage</code> to get the name of | |
119 * the language suitable for displaying to the user. Interestingly, | |
120 * the <code>getDisplayXXX</code> methods are themselves locale-sensitive | |
121 * and have two versions: one that uses the default locale and one | |
122 * that takes a locale as an argument and displays the name or country in | |
123 * a language appropriate to that locale. | |
124 * | |
125 * <P> | |
126 * ICU provides a number of classes that perform locale-sensitive | |
127 * operations. For example, the <code>NumberFormat</code> class formats | |
128 * numbers, currency, or percentages in a locale-sensitive manner. Classes | |
129 * such as <code>NumberFormat</code> have a number of convenience methods | |
130 * for creating a default object of that type. For example, the | |
131 * <code>NumberFormat</code> class provides these three convenience methods | |
132 * for creating a default <code>NumberFormat</code> object: | |
133 * \htmlonly<blockquote>\endhtmlonly | |
134 * <pre> | |
135 * UErrorCode success = U_ZERO_ERROR; | |
136 * Locale myLocale; | |
137 * NumberFormat *nf; | |
138 * | |
139 * nf = NumberFormat::createInstance( success ); delete nf; | |
140 * nf = NumberFormat::createCurrencyInstance( success ); delete nf; | |
141 * nf = NumberFormat::createPercentInstance( success ); delete nf; | |
142 * </pre> | |
143 * \htmlonly</blockquote>\endhtmlonly | |
144 * Each of these methods has two variants; one with an explicit locale | |
145 * and one without; the latter using the default locale. | |
146 * \htmlonly<blockquote>\endhtmlonly | |
147 * <pre> | |
148 * nf = NumberFormat::createInstance( myLocale, success ); delete n
f; | |
149 * nf = NumberFormat::createCurrencyInstance( myLocale, success ); delete n
f; | |
150 * nf = NumberFormat::createPercentInstance( myLocale, success ); delete n
f; | |
151 * </pre> | |
152 * \htmlonly</blockquote>\endhtmlonly | |
153 * A <code>Locale</code> is the mechanism for identifying the kind of object | |
154 * (<code>NumberFormat</code>) that you would like to get. The locale is | |
155 * <STRONG>just</STRONG> a mechanism for identifying objects, | |
156 * <STRONG>not</STRONG> a container for the objects themselves. | |
157 * | |
158 * <P> | |
159 * Each class that performs locale-sensitive operations allows you | |
160 * to get all the available objects of that type. You can sift | |
161 * through these objects by language, country, or variant, | |
162 * and use the display names to present a menu to the user. | |
163 * For example, you can create a menu of all the collation objects | |
164 * suitable for a given language. Such classes implement these | |
165 * three class methods: | |
166 * \htmlonly<blockquote>\endhtmlonly | |
167 * <pre> | |
168 * static Locale* getAvailableLocales(int32_t& numLocales) | |
169 * static UnicodeString& getDisplayName(const Locale& objectLocale, | |
170 * const Locale& displayLocale, | |
171 * UnicodeString& displayName) | |
172 * static UnicodeString& getDisplayName(const Locale& objectLocale, | |
173 * UnicodeString& displayName) | |
174 * </pre> | |
175 * \htmlonly</blockquote>\endhtmlonly | |
