Class Localizer

java.lang.Object
  org.apache.openjpa.lib.util.Localizer

public class Localizer
extends Object

The Localizer provides convenient access to localized strings. It inlcudes built-in support for parameter substitution through the use of the MessageFormat utility. Strings are stored in per-package Properties files. The property file for the default locale must be named localizer.properties. Additional locales can be supported through additional property files using the naming conventions specified in the ResourceBundle class. For example, the german locale could be supported through a localizer_de_DE.properties file.
