Interface GwtLocale

All Superinterfaces:

java.lang.Comparable<GwtLocale>

All Known Implementing Classes:

GwtLocaleImpl

public interface GwtLocale
extends java.lang.Comparable<GwtLocale>

Class representing GWT locales and conversion to/from other formats. These locales correspond to BCP47.

DEFAULT_LOCALE

static final java.lang.String DEFAULT_LOCALE

See Also:

Constant Field Values

compareTo

int compareTo(GwtLocale o)

The default comparison is a lexical ordering.

Specified by:

compareTo in interface java.lang.Comparable<GwtLocale>

getAliases

java.util.List<GwtLocale> getAliases()

Return the list of aliases for this locale. The canonical form of the current locale is always first on the list. Language/region codes have changed over time, so some systems continue to use the older codes. Aliases allow GWT to use the official Unicode CLDR locales while still interoperating with such systems.

Returns:

alias list

getAsString

java.lang.String getAsString()

Return the locale as a fixed-format string suitable for use in searching for localized resources. The format is language_Script_REGION_VARIANT, where language is a 2-8 letter code (possibly with 3-letter extensions), script is a 4-letter code with an initial capital letter, region is a 2-character country code or a 3-digit region code, and variant is a 5-8 character (may be 4 if the first character is numeric) code. If a component is missing, its preceding _ is also omitted. If this is the default locale, the empty string will be returned.

Returns:

String representing locale

getCanonicalForm

GwtLocale getCanonicalForm()

Returns this locale in canonical form.

• Deprecated language/region tags are replaced with official versions
• Default scripts are removed (including region-specific defaults for Chinese)
• no/nb/nn are normalized
• Default region for zh_Hans and zh_Hant if none specified

Returns:

GwtLocale instance

getCompleteSearchList

java.util.List<GwtLocale> getCompleteSearchList()

Return the complete list of locales to search for the current locale. This list will always start with the canonical form of this locale, and end with "default", and include all appropriate aliases along the way.

Returns:

search list

getInheritanceChain

java.util.List<GwtLocale> getInheritanceChain()

Return a list of locales to search for, in order of preference. The current locale is always first on the list. Aliases are not included in the list -- use getAliases() to expand those.

Returns:

inheritance list

getLanguage

java.lang.String getLanguage()

Returns:

the language portion of the locale, or null if none.

getLanguageNotNull

java.lang.String getLanguageNotNull()

Returns:

the language portion of the locale, or the empty string if none.

getRegion

java.lang.String getRegion()

Returns:

the region portion of the locale, or null if none.

getRegionNotNull

java.lang.String getRegionNotNull()

Returns:

the region portion of the locale, or the empty string if none.

getScript

java.lang.String getScript()

Returns:

the script portion of the locale, or null if none.

getScriptNotNull

java.lang.String getScriptNotNull()

Returns:

the script portion of the locale, or the empty string if none.

getVariant

java.lang.String getVariant()

Returns:

the variant portion of the locale, or null if none.

getVariantNotNull

java.lang.String getVariantNotNull()

Returns:

the variant portion of the locale, or the empty string if none.

inheritsFrom

boolean inheritsFrom(GwtLocale parent)

Return true if this locale inherits from the specified locale. Note that locale.inheritsFrom(locale) is false -- if you want that to be true, you should just use locale.getInheritanceChain().contains(x).

Parameters:

parent - locale to test against

Returns:

true if parent is an ancestor of this locale

isDefault

boolean isDefault()

Returns:

true if this is the default or root locale.

toString

java.lang.String toString()

Overrides:

toString in class java.lang.Object

Returns:

a human readable string -- "default" or the same as getAsString().

usesSameScript

boolean usesSameScript(GwtLocale other)

Checks if this locale uses the same script as another locale.

Parameters:

other -

Returns:

true if the scripts are the same
