UML PROFILE FOR SAVECCM - Research

SaveUML profile
6.3.3.14 SaveDelegation
The delegation in SaveCCM is used for connecting a port of a component to a
port of its subcomponent. Delegation is used while defining the internal structure of
a composite component or an assembly. In the delegation relationship, data or
signals from a components/subcomponents port are delegated to
subcomponents/components port. Therefore, either a components port depends
on its internal port for some data or signal, or a components internal port depends
on a components port for data or signal. Considering the semantics, the UML
dependency relationship seemed suitable as a base classifier for the delegation
stereotype. The delegation connection connects ports of the same direction.
Base classifier: Dependency
Tagged values:
• Source : String. The source of the delegation – the starting port.
• Destination : String. The destination of the delegation – the ending port
Constraints:
[1] DelegationComplex: see the SaveConnection constraint [1].
[2] DelegationComposite: Either source or destination port must be owned by a
composite or assembly component (the component with SaveAssembly or
SaveComposite stereotype applied).
[3] DelegationConformance: This constraint checks the type conformance of the
connected ports. The type conformance condition is the same as in SaveIDE tool.
The condition checks the direction of the connected ports, their types and as
circumstances require, the equality of their "Type" tagged values.
[4] DelegationCyclic: It is not allowed to have cyclic connection.
[5] DelegationNotUsage: Since Usage relationship is inherited from Dependency
relationship, then usage is a kind of dependency and it is possible to apply
SaveDelegation stereotype to usage relationship. Usage relationship is used for
modelling the SaveCCM connection (see section 6.3.3.10), therefore it is necessary
to check that SaveDelegation stereotype is applied to delegation relationship and
not to usage relationship.
[6] DelegationPorts: Source and destination port must have an appropriate stereotype
applied.
[7] NumberOfStereotypes: see the SaveAssembly constraint [6].
6.3.3.15 SaveFromComplex
A special kind of a connection is used to connect the complex connection to a
port of a component. The usage relationship is used as the base classifier based
on the same rationale with the basic component connection (see section 6.3.3.10).
