Row | Violation |
---|---|
1 | Unmatched statement close(true); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
2 | Unmatched statement throw new IOException("This instance of the CsvReader class has already been closed."); cannot be moved before or after the extracted code, because it throws exception(s) that should be caught by a try block that will be extracted |
3 | Unmatched throw new IOException("This instance of the CsvReader class has already been closed."); |
4 | Unmatched statement closed=true; cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
5 | The refactoring of the clones is infeasible, because the number of macthed statements is equal to zero |
