Precondition Violations (4)
Row |
Violation |
1 | Expression list.add(item) cannot be parameterized, because it has dependencies to/from statements that will be extracted |
2 | Expression list.remove(item) cannot be parameterized, because it has dependencies to/from statements that will be extracted |
3 | Expression list.add(item) is a void method call, and thus it cannot be parameterized |
4 | Expression list.remove(item) is a void method call, and thus it cannot be parameterized |
