Examples of org.apache.avalon.meta.info.ReferenceDescriptor

org.apache.avalon.meta.info.ReferenceDescriptor
This reference defines the type of interface required by a component. The type corresponds to the class name of the interface implemented by component. Associated with each classname is a version object so that different versions of same interface can be represented. @author Avalon Development Team @version $Revision: 1.1.1.1 $ $Date: 2003/09/24 08:15:09 $
