[icu enhancement] ICU's replacement for java.util.Locale
. Methods, fields, and other functionality specific to ICU are labeled '[icu]'. A class analogous to java.util.Locale
that provides additional support for ICU protocol. In ICU 3.0 this class is enhanced to support RFC 3066 language identifiers.
Many classes and services in ICU follow a factory idiom, in which a factory method or object responds to a client request with an object. The request includes a locale (the requested locale), and the returned object is constructed using data for that locale. The system may lack data for the requested locale, in which case the locale fallback mechanism will be invoked until a populated locale is found (the valid locale). Furthermore, even when a populated locale is found (the valid locale), further fallback may be required to reach a locale containing the specific data required by the service (the actual locale).
ULocale performs 'normalization' and 'canonicalization' of locale ids. Normalization 'cleans up' ICU locale ids as follows:
- language, script, country, variant, and keywords are properly cased
(lower, title, upper, upper, and lower case respectively) - hyphens used as separators are converted to underscores
- three-letter language and country ids are converted to two-letter equivalents where available
- surrounding spaces are removed from keywords and values
- if there are multiple keywords, they are put in sorted order
- POSIX ids are converted to ICU format IDs
- Legacy language tags (marked as “Type: grandfathered” in BCP 47) are converted to ICU standard form
canonicalize
can be called to convert the id to canonical form, or the canonicalInstance
factory method can be called.
Note: The actual locale is returned correctly, but the valid locale is not, in most cases.

Public constructors
ULocale
ULocale(localeID: String!)
[icu] Constructs a ULocale from a RFC 3066 locale ID. The locale ID consists of optional language, script, country, and variant fields in that order, separated by underscores, followed by an optional keyword list. The script, if present, is four characters long-- this distinguishes it from a country code, which is two characters long. Other fields are distinguished by position as indicated by the underscores. The start of the keyword list is indicated by '@', and consists of two or more keyword/value pairs separated by semicolons(';').
This constructor does not canonicalize the localeID. So, for example, "zh__pinyin" remains unchanged instead of converting to "zh@collation=pinyin". By default ICU only recognizes the latter as specifying pinyin collation. Use #createCanonical or canonicalize
if you need to canonicalize the localeID.
Parameters | |
---|---|
localeID |
String!: string representation of the locale, e.g: "en_US", "sy_Cyrl_YU", "zh__pinyin", "es_ES@currency=EUR;collation=traditional" |
ULocale
ULocale(
a: String!,
b: String!)
Convenience overload of ULocale(String, String, String) for compatibility with java.util.Locale.
See Also
ULocale
ULocale(
a: String!,
b: String!,
c: String!)
Constructs a ULocale from a localeID constructed from the three 'fields' a, b, and c. These fields are concatenated using underscores to form a localeID of the form a_b_c, which is then handled like the localeID passed to ULocale(String localeID)
.
Java locale strings consisting of language, country, and variant will be handled by this form, since the country code (being shorter than four letters long) will not be interpreted as a script code. If a script code is present, the final argument ('c') will be interpreted as the country code. It is recommended that this constructor only be used to ease porting, and that clients instead use the single-argument constructor when constructing a ULocale from a localeID.
Parameters | |
---|---|
a |
String!: first component of the locale id |
b |
String!: second component of the locale id |
c |
String!: third component of the locale id |

availableLocales: Array<ULocale!>!,
fallback: BooleanArray!
): ULocale!
[icu] Based on a HTTP formatted list of acceptable locales, determine an available locale for the user. NullPointerException is thrown if acceptLanguageList or availableLocales is null. If fallback is non-null, it will contain true if a fallback locale (one not in the acceptLanguageList) was returned. The value on entry is ignored. ULocale will be one of the locales in availableLocales, or the ROOT ULocale if if a ROOT locale was used as a fallback (because nothing else in availableLocales matched). No ULocale array element should be null; behavior is undefined if this is the case.

addLikelySubtags
static fun addLikelySubtags(loc: ULocale!): ULocale!
[icu] Adds the likely subtags for a provided locale ID, per the algorithm described in the following CLDR technical report: http://www.unicode.org/reports/tr35/#Likely_Subtags If the provided ULocale instance is already in the maximal form, or there is no data available available for maximization, it will be returned. For example, "sh" cannot be maximized, since there is no reasonable maximization. Otherwise, a new ULocale instance with the maximal form is returned. Examples: "en" maximizes to "en_Latn_US" "de" maximizes to "de_Latn_DE" "sr" maximizes to "sr_Cyrl_RS" "zh_Hani" maximizes to "zh_Hani_CN"
Parameters | |
---|---|
loc |

Return | |
---|---|
ULocale! |
The maximized ULocale instance. |
canonicalize
static fun canonicalize(localeID: String!): String!

Parameters | |
---|---|
localeID |
String!: the locale id |
Return | |
---|---|
String! |
the canonicalized id |
clone
fun clone(): Any!
This is for compatibility with Locale-- in actuality, since ULocale is immutable, there is no reason to clone it, so this API returns 'this'.
Return | |
---|---|
Any! |
a clone of this instance. |
Exceptions | |
---|---|
java.lang.CloneNotSupportedException |
if the object's class does not support the Cloneable interface. Subclasses that override the clone method can also throw this exception to indicate that an instance cannot be cloned. |
compareTo
fun compareTo(other: ULocale!): Int
Compares two ULocale for ordering.
Note: The order might change in future.
Parameters | |
---|---|
o |
the object to be compared. |
other |
ULocale!: the ULocale to be compared. |
Return | |
---|---|
Int |
a negative integer, zero, or a positive integer as this ULocale is less than, equal to, or greater than the specified ULocale. |
Exceptions | |
---|---|
java.lang.NullPointerException |
if other is null. |
java.lang.ClassCastException |
if the specified object's type prevents it from being compared to this object. |
createCanonical
static fun createCanonical(nonCanonicalID: String!): ULocale!
[icu] Creates a ULocale from the id by first canonicalizing the id according to CLDR.
Parameters | |
---|---|
nonCanonicalID |
String!: the locale id to canonicalize |
Return | |
---|---|
ULocale! |
the locale created from the canonical version of the ID. |
createCanonical
static fun createCanonical(locale: ULocale!): ULocale!
Creates a ULocale from the locale by first canonicalizing the locale according to CLDR.
Parameters | |
---|---|
locale |
ULocale!: the ULocale to canonicalize |
Return | |
---|---|
ULocale! |
the ULocale created from the canonical version of the ULocale. |
equals
fun equals(other: Any?): Boolean
Returns true if the other object is another ULocale with the same full name. Note that since names are not canonicalized, two ULocales that function identically might not compare equal.
Parameters | |
---|---|
obj |
the reference object with which to compare. |
Return | |
---|---|
Boolean |
true if this Locale is equal to the specified object. |
forLanguageTag
static fun forLanguageTag(languageTag: String!): ULocale!
Returns a locale for the specified IETF BCP 47 language tag string.
If the specified language tag contains any ill-formed subtags, the first such subtag and all following subtags are ignored. Compare to ULocale.Builder#setLanguageTag
which throws an exception in this case.
The following conversions are performed:
- The language code "und" is mapped to language "".
- The portion of a private use subtag prefixed by "lvariant", if any, is removed and appended to the variant field in the result locale (without case normalization). If it is then empty, the private use subtag is discarded:
ULocale loc; loc = ULocale.forLanguageTag("en-US-x-lvariant-icu4j); loc.getVariant(); // returns "ICU4J" loc.getExtension('x'); // returns null loc = Locale.forLanguageTag("de-icu4j-x-URP-lvariant-Abc-Def"); loc.getVariant(); // returns "ICU4J_ABC_DEF" loc.getExtension('x'); // returns "urp"
- When the languageTag argument contains an extlang subtag, the first such subtag is used as the language, and the primary language subtag and other extlang subtags are ignored:
ULocale.forLanguageTag("ar-aao").getLanguage(); // returns "aao" ULocale.forLanguageTag("en-abc-def-us").toString(); // returns "abc_US"
- Case is normalized. Language is normalized to lower case, script to title case, country to upper case, variant to upper case, and extensions to lower case.
This implements the 'Language-Tag' production of BCP 47, and so supports legacy language tags (marked as “Type: grandfathered” in BCP 47) (regular and irregular) as well as private use language tags.
Stand-alone private use tags are represented as empty language and extension 'x-whatever', and legacy tags are converted to their canonical replacements where they exist.
Note that a few legacy tags have no modern replacement; these will be converted using the fallback described in the first paragraph, so some information might be lost.
Note: there is no guarantee that toLanguageTag
and forLanguageTag
will round-trip.

Return | |
---|---|
ULocale! |
The locale that best represents the language tag. |
Exceptions | |
---|---|
java.lang.NullPointerException |

Return | |
---|---|
ULocale! |
The minimized ULocale instance. |

toLanguageTag
fun toLanguageTag(): String!
Returns a well-formed IETF BCP 47 language tag representing this locale.
If this ULocale
has a language, script, country, or variant that does not satisfy the IETF BCP 47 language tag syntax requirements, this method handles these fields as described below:
Language: If language is empty, or not well-formed (for example "a" or "e2"), it will be emitted as "und" (Undetermined).
Script: If script is not well-formed (for example "12" or "Latin"), it will be omitted.
Country: If country is not well-formed (for example "12" or "USA"), it will be omitted.
Variant: If variant is well-formed, each sub-segment (delimited by '-' or '_') is emitted as a subtag. Otherwise:
- if all sub-segments match
[0-9a-zA-Z]{1,8}
(for example "WIN" or "Oracle_JDK_Standard_Edition"), the first ill-formed sub-segment and all following will be appended to the private use subtag. The first appended subtag will be "lvariant", followed by the sub-segments in order, separated by hyphen. For example, "x-lvariant-WIN", "Oracle-x-lvariant-JDK-Standard-Edition". - if any sub-segment does not match
[0-9a-zA-Z]{1,8}
, the variant will be truncated and the problematic sub-segment and all following sub-segments will be omitted. If the remainder is non-empty, it will be emitted as a private use subtag as above (even if the remainder turns out to be well-formed). For example, "Solaris_isjustthecoolestthing" is emitted as "x-lvariant-Solaris", not as "solaris".
Note: Although the language tag created by this method is well-formed (satisfies the syntax requirements defined by the IETF BCP 47 specification), it is not necessarily a valid BCP 47 language tag. For example,
new Locale("xx", "YY").toLanguageTag();
Return | |
---|---|
String! |
a BCP47 language tag representing the locale |

String!: the input locale keyword (either BCP 47 Unicode locale extension key or legacy key). |
Return | |
---|---|
String! |
the well-formed legacy key, or null if the specified keyword cannot be mapped to a well-formed legacy key. |

toLegacyType
static fun toLegacyType(
keyword: String!,
value: String!
): String!
[icu] Converts the specified keyword value (BCP 47 Unicode locale extension type, or legacy type or type alias) to the canonical legacy type. For example, the legacy type "phonebook" is returned for the input BCP 47 Unicode locale extension type "phonebk" with the keyword "collation" (or "co").
When the specified keyword is not recognized, but the specified value satisfies the syntax of legacy key, or when the specified keyword allows 'variable' type and the specified value satisfies the syntax, the lower-case version of the input value will be returned. For example, toLegacyType("Foo", "Bar")
returns "bar", toLegacyType("vt", "00A4")
returns "00a4".
Parameters | |
---|---|
keyword |
String!: the locale keyword (either legacy keyword such as "collation" or BCP 47 Unicode locale extension key such as "co"). |
value |
String!: the locale keyword value (either BCP 47 Unicode locale extension type such as "phonebk" or legacy keyword value such as "phonebook"). |
Return | |
---|---|
String! |
the well-formed legacy type, or null if the specified keyword value cannot be mapped to a well-formed legacy type. |

toLocale
fun toLocale(): Locale!
[icu] Converts this ULocale object to a java.util.Locale
.
Return | |
---|---|
Locale! |
a java.util.Locale that either exactly represents this object or is the closest approximation. |
toString
fun toString(): String
Returns a string representation of this object.
Return | |
---|---|
String |
a string representation of the object. |
toUnicodeLocaleKey
static fun toUnicodeLocaleKey(keyword: String!): String!
[icu] Converts the specified keyword (legacy key, or BCP 47 Unicode locale extension key) to the equivalent BCP 47 Unicode locale extension key. For example, BCP 47 Unicode locale extension key "co" is returned for the input keyword "collation".
When the specified keyword is unknown, but satisfies the BCP syntax, then the lower-case version of the input keyword will be returned. For example, toUnicodeLocaleKey("ZZ")
returns "zz".
Parameters | |
---|---|
keyword |
String!: the input locale keyword (either legacy key such as "collation" or BCP 47 Unicode locale extension key such as "co"). |
Return | |
---|---|
String! |
the well-formed BCP 47 Unicode locale extension key, or null if the specified locale keyword cannot be mapped to a well-formed BCP 47 Unicode locale extension key. |

toUnicodeLocaleType
static fun toUnicodeLocaleType(
keyword: String!,
value: String!
): String!
[icu] Converts the specified keyword value (legacy type, or BCP 47 Unicode locale extension type) to the well-formed BCP 47 Unicode locale extension type for the specified keyword (category). For example, BCP 47 Unicode locale extension type "phonebk" is returned for the input keyword value "phonebook", with the keyword "collation" (or "co").
When the specified keyword is not recognized, but the specified value satisfies the syntax of the BCP 47 Unicode locale extension type, or when the specified keyword allows 'variable' type and the specified value satisfies the syntax, the lower-case version of the input value will be returned. For example, toUnicodeLocaleType("Foo", "Bar")
returns "bar", toUnicodeLocaleType("variableTop", "00A4")
returns "00a4".
Parameters | |
---|---|
keyword |
String!: the locale keyword (either legacy key such as "collation" or BCP 47 Unicode locale extension key such as "co"). |
value |
String!: the locale keyword value (either legacy type such as "phonebook" or BCP 47 Unicode locale extension type such as "phonebk"). |
Return | |
---|---|
String! |
the well-formed BCP47 Unicode locale extension type, or null if the locale keyword value cannot be mapped to a well-formed BCP 47 Unicode locale extension type. |
