Header

@Entity

class Header(var dataID: Long? = null, elements: MutableList<HeaderElement> = LinkedList(), var instance: Instance? = null)

The Header contains the information which IObjects of an Instance are accessible from the outside, i.e., which objects can be targeted by AssociationRelations. A Header only exists in Fragments carrying an Instance. The individual objects are defined as HeaderElements. The Composition defines if an object is publicly visible or not (non-composition objects are always public). As soon as a IObject is created that is public according to its type, it is added as a HeaderElement

Properties

dataID

var dataID: Long?

Technical database (JPA) identifier used for relation joins. The dataID is system specific and not exported to XML. It must not be used to identify elements in distributed use-cases. It should not be used to identify elements from outside the service. All model elements provide other suitable identifiers to be used.

instance

var instance: Instance?
