AggregationKind [message #1061814]

I am using acceleo to generate an XSD from a UML model.

I want to be able to create different types of structures depending the type of association (i.e. Composition, Shared Aggregation, None).

A sample piece of Test Code below gives you the idea...

--- Code ---
[for (anAssociation : Association | aClass.getAssociations())]
[if( anAssociation.attribute.aggregation <--- ) /]
...
[/if]
[/for]
--- End Code ---

What do I actually do with the AggregationKind entity to determine what type of aggregation it is?

Help much appreciated.

I Mark the aggreagation kind is a property of the association's member ends.
You shold thus look for

anAssociation.memberEnd->at(1).aggregation

and

anAssociation.memberEnd->at(2).aggregation

See http://lowcoupling.com/post/47801917915/understanding-uml-associations
for further details about UML Associations

Hi,

I assume that AggregationKind is an enumeration, so in order to compare it you would have to do something like this:

[if(myObject.aggregation = Aggregation::composite)]composite[/if]

hi guy,
you can do dirrectly get your aggregation, inheritance and others. Maybe it can be better.
You can do:
p.aggregation.toString().strcmp('composite') --> For acomposition,
p.aggregation.toString().strcmp('shared') --> For an aggregation
