Elementtype for Aggregate [message #1750240]

I am configuring a toolbox for shapes (elements) and edges (relationships) and have the need to have an aggregate-relationship in the toolbox. I have succeeded to add an association, but I also need to set the aggregate property to "Aggregate".

I want to avoid to have to "program" (in Java) and want do it descriptable instead and hope to find a solution between some of the rules (for setting stereotypes etc).

1. Is it possible to set the aggregate property descriptable?
2. If yes, how it is done?

Thanks in advance!

Best regards, Thomas Gericke

Hi,

I have never used it but I think you can do the requested operation without code using SetValue Advice.

The procedure :
1- create a new ElementTypeConfigurationModel (wizard accessible through CTRL-N)
2- create new Specialization type that specialize the Metamodel type for UML::association
3- create a new SetValue advice and refere the feature to set and the value
4- refere your ElementTypeConfigurationModel throuth the following extension point "org.eclipse.papyrus.infra.types.core.elementTypeSetConfiguration"

Best regards,
Xavier

Hi,

Xavier made the correct suggestion, unfortunately it's not possible for the moment to set the aggregation at Shared in a pure model way.

This is tracked for SysML 1.4 in this bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=507601

You may do it in java, see : https://git.eclipse.org/c/papyrus/org.eclipse.papyrus-sysml.git/tree/core/org.eclipse.papyrus.sysml14.service.types/src/org/eclipse/papyrus/sysml14/service/types/advice/SharedAssociationEditHelperAdvice.java

Benoit

Thank you so much!

I went the "Java way" and implemented both an aggregate and a composite helper advice.

Great help! And thanks once again!

Best regards, Thomas
