public GwtLocaleFactoryImpl()
Method Detail

clear

public void clear()
Clear an embedded cache of instances when they are no longer needed.

Note that GwtLocale instances constructed after this is called will not maintain identity with instances constructed before this call.

fromComponents

public GwtLocale fromComponents(java.lang.String language,
                                java.lang.String script,
                                java.lang.String region,
                                java.lang.String variant)
Description copied from interface: GwtLocaleFactory
Construct a GWT locale from its component parts. Null or empty strings are accepted for parts not present.

Specified by:
fromComponents in interface GwtLocaleFactory
Returns:
GwtLocale instance, unique for a given set of values

fromString

public GwtLocale fromString(java.lang.String localeName)
Description copied from interface: GwtLocaleFactory
Get a GWT locale from a string conforming to a subset of BCP47 (specifically assuming extension tags are not present, at most one variant is present, and grandfathered tags are not supported; also private-use tags are only supported for the entire tag). Only minimal validation of BCP47 tags is performed, and will continue with what it is able to parse if unexpected input is encountered. A null or empty string is treated as the default locale.

Specified by:
fromString in interface GwtLocaleFactory
Returns:
a locale instance, always the same one for a given localeName
Throws:
java.lang.IllegalArgumentException - if the supplied locale does not match BCP47 structural requirements.

getDefault

public GwtLocale getDefault()
Description copied from interface: GwtLocaleFactory
Returns an instance of the default locale.

Specified by:
getDefault in interface GwtLocaleFactory
