Implements abstract java.time.format.DateTimeFormatterPatternProvider.getDateTimeFormatterPattern.

Doc from java.time.format.DateTimeFormatterPatternProvider.getDateTimeFormatterPattern.

Returns the localized pattern string for the date style, time style, calendar type, and locale. Either dateStyle or timeStyle may be null. In such cases, the returned pattern represents only the time or only the date, respectively. If both are null, an IllegalArgumentException is thrown.

public String getDateTimeFormatterPattern(String requestedTemplate, String calType, Locale locale)

Implements abstract java.time.format.DateTimeFormatterPatternProvider.getDateTimeFormatterPattern.

Doc from java.time.format.DateTimeFormatterPatternProvider.getDateTimeFormatterPattern.

Returns the localized pattern string for the requested template, calendar type, and locale. The requestedTemplate must match the regular expression described in DateTimeFormatterBuilder#appendLocalized(String); otherwise, an IllegalArgumentException is thrown.

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.
