Generalizations on associations?
--------------------------------
Key: UMLMETA-56
URL: http://jira.andromda.org/browse/UMLMETA-56
Project: UML Metafacades
Type: New Feature
Reporter: Andy Jones
Assigned to: Wouter Zoons
I posted the following message on the general AndroMDA site and Chad Brandon
suggested I log it here:
It appears that the AssociationFacade extends from ModelElementFacade:
(http://team.andromda.org/docs/andromda-metafacades-uml/apidocs/org/andromda/metafacades/uml/AssociationFacade.html)
Whereas ClassifierFacade extends from GeneralizableElementFacade:
(http://team.andromda.org/docs/andromda-metafacades-uml/apidocs/org/andromda/metafacades/uml/ClassifierFacade.html)
The UML 1.4 specifications state that both a Classifier and an Association are
subclasses of GeneralizableElements, and tools such as MagicDraw support
generalizations on associations.
UML 1.4:
http://www.andromda.org/andromda-metafacades/resources/UML14Metamodel.pdf
It is quite important for our application that we can specify that certain
associations (say between two abstract classes) are abstract, and that other
associations (say between two sub-classes) extend from the abstract association.
At the moment I'm using a fix of putting signals in the association
documentation but it would be preferable if the Metafacade could support the
features of:
- Abstract associations
- Generalizations on associations.
thanks
