public class EndpointHandler<B> extends ReferenceableHandler<B>
EndpointHandler manages Endpoint objects. These describe the network addresses where services are running. They are used by connection objects to describe the service that the connector should call. They are linked to servers to show their network address where the services that they are hosting are running. EndpointHandler runs server-side in the OMAG Server Platform and retrieves Endpoint entities through the OMRSRepositoryConnector via the generic handler and repository handler.
