public abstract class GettextResource
extends java.util.ResourceBundle

This class implements the main GNU libintl functions in Java.

Using the GNU gettext approach, compiled message catalogs are normal Java ResourceBundle classes and are thus interoperable with standard ResourceBundle based code.

The main differences between the Sun ResourceBundle approach and the GNU gettext approach are:

- In the Sun approach, the keys are abstract textual shortcuts. In the GNU gettext approach, the keys are the English/ASCII version of the messages.
- In the Sun approach, the translation files are called "Resource_locale.properties" and have non-ASCII characters encoded in the Java `\``unnnn` syntax. Very few editors can natively display international characters in this format. In the GNU gettext approach, the translation files are called "Resource.locale.po" and are in the encoding the translator has chosen. Many editors can be used. There are at least three GUI translating tools (Emacs PO mode, KDE KBabel, GNOME gtranslator).
- In the Sun approach, the function `ResourceBundle.getString` throws a `MissingResourceException` when no translation is found. In the GNU gettext approach, the `gettext` function returns the (English) message key in that case.
- In the Sun approach, there is no support for plural handling. Even the most elaborate MessageFormat strings cannot provide decent plural handling. In the GNU gettext approach, we have the `ngettext` function.

To compile GNU gettext message catalogs into Java ResourceBundle classes, the `msgfmt` program can be used.
