isSupportedLocale back to summary

isSupportedLocale	back 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 `Locale`s 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. Annotations @Override
