@ExtensionPoint
public interface InformationService<T extends Ref>
extends Ordered

Marker interface for information services.

An InformationService provides some sort of information about something. Plug-ins should normally implement this as a entry point.

To provide an implementation of InformationService, register an instance of this interface as an OSGi service with the property Constants#GENERIC_SERVICE_CLASSNAME set to the name of the Class that this InformationService provides information for, and the property KEY_SERVICE_ID set to a unique identifier for your implementation.
