Detailed Model

The EndpointReference and Endpoint have a number of fields and a status which indicates what they are connected to and how they will be processed. Both structures are externalizable. In the Endpoint case this allows a distributed registry of endpoints to be maintained. In the EndpointReference case this allows ServiceReferences to be serialized between remote components as called for in the SCA specifications.
