## org.fourthline.cling.model
Class ServiceReference

    java.lang.Object
      org.fourthline.cling.model.ServiceReference

    public class ServiceReference

extends Object

Combines a `UDN` and a `ServiceId`.

A service reference is useful to remember a service. For example, if a control point has accessed a service one, it can remember the service with `Service.getReference()`. Before every action invocation, it can now resolve the reference to an actually registered service with `Registry.getService(ServiceReference)`. If the registry doesn't return a service for the given reference, the service is currently not available.

This simplifies implementing disconnect/reconnect behavior in a control point.
