Hi,

I'm a beginner with Acceleo, and I have a little question to improve my PHP class file generation from the model.

I have two class "A" and "B" linked by a "one to many" association in the UML model, and I would like to know how to retrieve a "Class" object from the end of the association.

On the property of my class "A", I can retrieve the name of the class "B" which is at the end of the association :

[p.association.endType->last().name/]

But in my class A, I would like to read information about my class B pointed by the association like this :

[getValue(myClassB.getAppliedStereotype('default::Classifier'), 'persistence').toString()/]

How can I do that?
Or, How can I retrieve a "Class" object from her String name?
I haven't see a getClass('String') method or something like this Sad

Thanks for your help,

David

Hi,

I think that the "inverse()" operation may help you in your case. It will allow you to find out the elements that are linked to a given element, it should allow you to find your association and then your class "b" from an "a" element.

Hi,

Thank you for your help. I suppose you talk about "eInverse()" operation in fact? (instead of inverse())
I have tried this one but, from my association, I can find only the property and the class A, but not the class B.

But the solution was more simple in fact! Smile

p.association.endType->last().oclAsType(Class)

I understand now the "oclAsType" usage Smile
