isSupportedLocaleback to summary
public boolean isSupportedLocale(Locale locale)

Overrides java.util.spi.LocaleServiceProvider.isSupportedLocale.

Doc from java.util.spi.LocaleServiceProvider.isSupportedLocale.

Returns true if the given locale is supported by this locale service provider. The given locale may contain extensions that should be taken into account for the support determination.

The default implementation returns true if the given locale is equal to any of the available Locales returned by getAvailableLocales() with ignoring any extensions in both the given locale and the available locales. Concrete locale service provider implementations should override this method if those implementations are Locale extensions-aware. For example, DecimalFormatSymbolsProvider implementations will need to check extensions in the given locale to see if any numbering system is specified and can be supported. However, CollatorProvider implementations may not be affected by any particular numbering systems, and in that case, extensions for numbering systems should be ignored.
