Is there any option in Eclipse modeling framework to choose different arrow than Association or Generalization arrow? I mean something like “aggregation” or association line without arrow in the end. In EMF I can “draw” only this: —> and this —<>. But there are much more like: —|>, or —(+) and so on…
Ecore itself supports only EClass.eReferences (association) and EClass.eSuperTypes (generalization). EReferences can be bidirectional in which cases there is no arrow head, and an EReference can be a containment, in which case there is a black diamond. That’s all there is. You’ll need a UML tool like Papyrus to support the full UML repertoire.
