Class I18NHelper

java.lang.Object
  |
  +--javax.jdo.I18NHelper

public class I18NHelper
extends java.lang.Object

Helper class for constructing messages from bundles. The intended usage of this class is to construct a new instance bound to a bundle, as in

I18NHelper msg = I18NHelper.getInstance("javax.jdo.Bundle");

This call uses the class loader that loaded the I18NHelper class to find the specified Bundle. The class provides two overloaded getInstance methods allowing to specify a different class loader: getInstance(Class cls) looks for a bundle called "Bundle.properties" located in the package of the specified class object and getInstance(String bundleName,ClassLoader loader) uses the specified class loader to find the bundle.

Subsequently, instance methods can be used to format message strings using the text from the bundle, as in

throw new JDOFatalInternalException (msg.msg("ERR_NoMetadata", cls.getName()));
