invalidateOn

protected final void invalidateOn(org.eclipse.emf.ecore.EObject object,
                                  org.eclipse.emf.ecore.EStructuralFeature... features)

Tells this filter to invalidate the cached value at the object key, if one of the given features of the object is changed.

Parameters:

object - the object to monitor features of, also acts as the cache key.

features - the features to monitor.

invalidateOn

protected final void invalidateOn(org.eclipse.emf.ecore.EStructuralFeature... features)
