Precondition Violations (3)
Row |
Violation |
1 | Type org.eclipse.emf.common.util.EList<org.eclipse.emf.ecore.change.ListChange> of variable listChanges does not match with type java.util.List<org.eclipse.emf.ecore.util.FeatureMap.Entry> of variable removals |
2 | Unmatched statement removals=new BasicEList<Entry>(); cannot be moved before or after the extracted code, because it has dependencies to/from statements that will be extracted |
3 | Unmatched return listChanges; |
