  • Field Details

    • STANDARD

      public static final DecimalStyle STANDARD
      The standard set of non-localized decimal style symbols.

      This uses standard ASCII characters for zero, positive, negative and a dot for the decimal point.

  • Method Details

    • getAvailableLocales

      public static Set<Locale> getAvailableLocales()
      Lists all the locales that are supported.

      The locale 'en_US' will always be present.

      Returns:
      a Set of Locales for which localization is supported

    • ofDefaultLocale

      public static DecimalStyle ofDefaultLocale()
      Obtains the DecimalStyle for the default FORMAT locale.

      This method provides access to locale sensitive decimal style symbols.

      This is equivalent to calling of(Locale.getDefault(Locale.Category.FORMAT)).

      Returns:
      the decimal style, not null
      See Also:
      Locale.Category.FORMAT

    • of

      public static DecimalStyle of​(Locale locale)
      Obtains the DecimalStyle for the specified locale.

      This method provides access to locale sensitive decimal style symbols. If the locale contains "nu" (Numbering System) and/or "rg" (Region Override) Unicode extensions, returned instance will reflect the values specified with those extensions. If both "nu" and "rg" are specified, the value from the "nu" extension supersedes the implicit one from the "rg" extension.

      Parameters:
      locale - the locale, not null
      Returns:
      the decimal style, not null
