public class AssociationID<C>
extends ConstantObject<AssociationID<C>>

An AssociationID is used by databases as a unique identifier for specific associations to single objects. Such as label, local similarity measure. There is no association possible without a specific AssociationID defined within this class.

An AssociationID provides also information concerning the class of the associated objects.
