MessageBundles classes extend this class, to implement a bundle. For Native Language Support (NLS), system of software internationalization. This interface is similar to the NLS class in eclipse.osgi.util.NLS class - initializeMessages() method resets the values of all static strings, should only be called by classes that extend from NLS (see TestMessages.java for reference) - performs validation of all message in a bundle, at class load time - performs per message validation at runtime - see NLSTest.java for usage reference MessageBundle classes may subclass this type.
