MessageReference

Implementation class supporting the referencing of a Message element

Specific fields

Reference Type Range Description
message Message 1..1

Inherited fields (from Relationship, AbstractRelationship)

Reference Type Range Description
realizedFlow AbstractInformationFlow 0..1

MessageReferencePkg

a container for message references elements

Common Types: Namespace, NamedElement, AbstractNamedElement, ModelElement, CapellaElement, TraceableElement, PublishableElement

Known Sub Types: InterfacePkg, DataPkg

Specific fields

Reference Type Range Description
ownedMessageReferences MessageReference 0..*

Inherited fields (from Structure)

Signal

A signal is a specification of send request instances communicated between objects. The receiving object handles the received request instances as specified by its receptions. The data carried by a send request (which was passed to it by the send invocation occurrence that caused that request) are represented as attributes of the signal. A signal is defined independently of the classifiers handling the signal occurrence [source: UML superstructure v2.2]

Common Types: AbstractNamedElement, ModelElement, Namespace, NamedElement, CapellaElement, TraceableElement, PublishableElement
