How to find if two model elements have the same children? [message #1806245]

Hi,

I was wondering if there is a utility function to determine if two model elements have the same children? For instance, if two classes in the transitions in a state-machine have the same event, guard, and effect.

If not, another way would be traversing through all the children and check one by one, I assume. Or can we simply compare ele1.eAllcontents() and ele2.eAllcontents() ?

Thanks,
Parsa

EcoreUtil.equals is helpful for testing for structural equality. It uses org.eclipse.emf.ecore.util.EcoreUtil.EqualityHelper which could be specialized to do structural equality checking some other way.
