org.openiaml.model.diagram.helpers.inference.EmfInferenceHandler

Wraps {@link EcoreInferenceHandler} with {@link AbstractTransactionalCommand}s, allowing EMF-based operations (such as {@link #setValue(EObject,EStructuralFeature,Object)}, {@link #createElement(EObject,EClass,EStructuralFeature)}) to execute within a transaction.

This will prevent "Cannot modify resource set without a write transaction" exceptions when trying to access the EMF objects directly.
