Hi,

I'd like to access the objects from the model in memory to use in another method. For this, i have to use a extension with External Java Action, like this https://www.eclipse.org/sirius/doc/specifier/general/Model_Operations.html#extensions

in the code bellow, i can access the information about style, but it's not what I want.

@Override
	public void execute(Collection<? extends EObject> selections, Map<String, Object> parameters) {
		for(EObject obj : selections) {
			TreeIterator<EObject> eAllContents = obj.eAllContents();
			while(eAllContents.hasNext()) {
				EObject next = eAllContents.next();
				EList<EAttribute> nameElement = next.eClass().getEAllAttributes();
			}
		}
	}

I want information about the packages, classes, attributes, etc of the model.
How can I do this? It's possible? Sorry, I'm a beginner in sirius.

Thanks

Maybe you must a change context Model Operations https://www.eclipse.org/sirius/doc/specifier/general/Model_Operations.html#goto before you call you extensions.

change context expression:

var:self

Hi,

Can you be more specific about the context?
From where your action is called?

Also external actions are not recommended. Prefer using services: https://www.eclipse.org/sirius/doc/specifier/general/Writing_Queries.html#service_methods

I'm using a popup menu to call a Java Action, in the method called I've got to access all the contents of the model to generate code.

You have to get the semantic elements from the representation element you get with:

((DRepresentationElement)obj).getTarget()
