AssociationRelation

@Entity

class AssociationRelation(var dataID: Long? = null, var uri: String = "", var name: String = "", var target: String = "", val cInterface: Interface? = null, var node: Node? = null)

The AssociationRelation models a directed association edge from one Node to another Node. The association is always owned by the starting Node.

Modicio Associations have no multiplicity
The target existence is an open property, i.e., it is only evaluated at runtime if an association is realizable
Associations are variability-aware. This is defined via the Interface

Constructors

AssociationRelation

constructor()

constructor(dataID: Long? = null, uri: String = "", name: String = "", target: String = "", cInterface: Interface? = null, node: Node? = null)

Properties

cInterface

val cInterface: Interface? = null

The Interface (refers to the ConnectionInterface ESI concept). The Interface specifies a set of (open) intervals and points in time-space an allowed target must be part of to fulfill this association. An AssociationRelation must have an Interface.

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.

name

var name: String

The name of the AssociationRelation. Uniqueness is optional but should be assured in a common Node

node

var node: Node?

Backlink to Node to improve traversal. This is not the target Node! But the owner of this element.

target

var target: String

The target Node that is the other end of instances of this relation.

uri

var uri: String

The unique naming URI of the AssociationRelation in its current Model. The uri must not take variant/version into account which is stored separately. A modicio URI is defined as a "xs:anyURI" base with the schema extension "modicio:.*"
