SoMoX/Development/SAMM to PCM Migration
< SoMoX | Development
Development Notes
ComponentType
- in SAMM: Super class of PrimitiveComponent and CompositeComponent
- in PCM: Enumeration type and NOT super class of basic and composite component!
-> be carefull when using automatic organize imports in eclipse!
CompleteComponentType vs. RepositoryComponent vs. ImplementationComponententType
In the Q-Impress deliverable, the mapping table between SAMM and PCM maps a SAMM ComponentType to a PCM CompleteComponentType. This is not valid for SoMoX because a CompleteComponentType is not compatible with an ImplementationComponentType or a BasicComponent. The latter is required to reference ServiceEffectSpecifications (SEFF) later on. One should use either a BasicComponent or a RepositoryComponent, depending on the requirements of the actually migrated code.
Interfaces
When the SAMM metamodel has been created, it was derived from the "simple" palladio interfaces. Meanwhile, the palladio meta model has been enhanced to specify different types of interfaces. At least event and operational interfaces should be treated explicitly.
