As you can see I am stuck with the use of a crossReferencer. I need a
Crossreferencer that is capable of telling me who are the Non-Containing
Parent or the ParentCrossReferencer of that Object. I have Attached the
try I have done, but as you can see, my last attempt pop me out a cast
exeption.
Here the principal problem I have is that I use wrapper. Therefore, The
Object in getChildren are not necessarily EOBJECT. I can Have an object
that wrap represent my referenced object, and therefore are not equal. I
don't know what to do hear? Can anyone suggest me something Please?
/**
* We check that the crossReferencedEObject is within the children of
the referencing Object.
* This method is heavy, it would be better to check the children
feature of the object against the reference.
*/
@SuppressWarnings("unchecked")
@Override
protected boolean crossReference(EObject object, EReference reference,
EObject crossReferencedEObject) {
if (super.crossReference(object, reference, crossReferencedEObject)) {
Collection<EObject> children = mydomain.getChildren(object) == null ?
Collections.EMPTY_LIST : mydomain.getChildren(object) ;
for(EObject child : children) {
if ( EcoreUtil.equals(child, crossReferencedEObject))
return true;
}
}
return false;
}
}
Please does any one has an Idea on how to solve this problem of
ParentCross-Referencer or Non-Containg Parent ?
Many thanks,
Maatari

Maatari,
This note of yours was posted only 6 minutes after the previous one...

Does this really return Collection<EObject>? I thought it was
Collection<?> and in fact you're likely getting wrappers returned as
children which aren't EObjects...

Anyway, as I suggested in the other post, I think you just want to do an
== test on the reference.
