Class EmptyResourceI18nConcern

java.lang.Object

io.rincl.EmptyResourceI18nConcern

All Implemented Interfaces:

io.csar.Concern, LocaleSelectable, ResourceI18nConcern, ResourcesFactory

public class EmptyResourceI18nConcern
extends Object
implements ResourceI18nConcern

Resource internationalization concern that returns an empty set of resources.

The locale retrieval and setting methods merely delegate to the JVM defaults.

This implementation is useful for use in an unconfigured context in which all calling code provides default resources in the case of a missing resource.
