[Acceleo] get referencing objects to self [message #677392] Wed, 08 June 2011 11:42 Go to next message

Hello,
i have the following problem:
In the model that is passed to me, there are two classes (just for this example):
"Implementation" and "Entity",
An implementation references to the entity it implements. On the other hand, the entity does not know its implementations.
My template generates for entities, but now i want to list all implementations of an entity. So my question is if there is a way to get all objects, that are referencing to an entity object. "Implementation" and "Entity" do not share a root, and changing the model is out of the question unfortunately.

Thanks for any help Smile

Hi,

That is the role of the eInverse operation : [entity.eInverse()/] will print out all objects referencing 'entity'. [entity.eInverse(Implementation)/] will print out all objects of type "Implementation" referencing entity.

OMG

Thanks a lot Smile
I feel so incredibly dumb not reading through the operations reference :\
I'm a total noob to java/eclipse/acceleo and i just ended up writing a class that iterates over a resource passed by an acceleo invoke, finding implementations referencing to entities and returning them Very Happy

I guess i deserve the punishment of having lost two hours^^ (although i learned quite a bit)


Again, thanks Smile
