java.lang.Object
org.gatein.pc.portlet.impl.info.ResourceBundleManager
public class ResourceBundleManager extends Object

Manage a set of resource bundles. Obtention of bundles is delegated to a ResourceBundleFactory. A bundle obtained successfully is cached in order to avoid the potential expensive cost of the bundle retrieval.

The manager can also be used to build LocalizedString object from the loaded bundles.

    • getLocalizedValue

      public org.gatein.common.i18n.LocalizedString getLocalizedValue(String key, String defaultValue) throws IllegalArgumentException
      Return a localized value constructed from the various resource bundles. The supported locales of the manager are used in combination with the specified key. The default value is used if no value is found for the Locale.ENGLISH. Two successive calls to this method may not return identical results since the returned LocalizedString is built using the bundles known by the manager.
      Parameters:
      key - the key to lookup in the bundles
      defaultValue - the default value
      Returns:
      the localized string
      Throws:
      IllegalArgumentException - if the key of the default value is null

    • getResourceBundle

      public ResourceBundle getResourceBundle(Locale locale) throws IllegalArgumentException
      Return a bundle for the given locale. If the complete locale (language + country + variant) does not exist then it falls back to (language + country) or (language) or the default file. When the resource bundle object is found and was not in the global map, it put it in that map with a copy on write.
      Parameters:
      locale - the locale we want a bundle for
      Returns:
      a bundle for the locale or null if not suitable bundle is found.
      Throws:
      IllegalArgumentException - if the locale is null
