Response Animation Emitter
A ModelElementObserver that emits an AnimationEvent.ResponseObserved each time a Response (including its time-weighted subtype TWResponse) or a Counter is observed. Setting a response's or counter's value fires a Status.UPDATE notification, which routes here as update.
Attach one instance to each statistical variable you want to animate (response.attachModelElementObserver(emitter)); a single instance can observe many variables because update receives the element that fired.
Parameters
name
optional observer name
