Precondition Violations (3)
Row |
Violation |
1 | Unmatched statement hasChanged=true; cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
2 | Unmatched return true; |
3 | The refactoring of the clones is infeasible, because the number of macthed statements is equal to zero |
