java.lang.Object
   org.apache.commons.discovery.resource.names.ResourceNameDiscoverImpl
      org.apache.commons.discovery.resource.names.DiscoverNamesInAlternateManagedProperties

All Implemented Interfaces:
ResourceNameDiscover

Recover resource name from Managed Properties, using OLD property names. This class maintains a mapping between old names and (new) the class names they represent. The discovery mechanism uses the class names as property names.
