evaluate method

@override List<Fact> evaluate(Map<String, List<List<Object>>> facts, Map<String, List<List<Object>>> derived)

Evaluates the rule and returns derived facts.

Implementation

@override
List<Fact> evaluate(
  Map<String, List<List<Object>>> facts,
  Map<String, List<List<Object>>> derived,
) {
  final result = <Fact>[];
  final stores = facts['StoreField'] ?? [];
  final pointsTo = getCombined('VarPointsTo', facts, derived);

  for (final store in stores) {
    final baseVar = store[0];

    for (final pt in pointsTo) {
      if (pt[0] == baseVar) {
        result.add(Fact('Mutable', [pt[1]]));
      }
    }
  }

  return result;
}
