Hi !

I need to get the EClass of a specific EObject and all EObjects of a specific EClass. I would like to write this on a pattern that will fit for all models , like this for example :

pattern getEClass(o : EObject) {
EObject.eClass();
}

Is there any way to do this ? It is very important to be able to find for a specific Eobject its EClass. Thank you !

Hi,

if you wish to know all instances of a given eClass:

pattern foo(bar) = {
MyFavoriteEClass(bar); 
// write here any other constraint you want to put on 'bar'
}

Currently, you cannot query the type of an eObject using EMF-IncQuery - but hey, you can easily do it in Java, using the .eClass() method.
