Precondition Violations (4)
Row |
Violation |
1 | Unmatched return true; |
2 | Unmatched statement _rowElem=_rowIter.next(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
3 | Unmatched return true; |
4 | The refactoring of the clones is infeasible, because classes net.sourceforge.squirrel_sql.fw.sql.MetaDataListDataSet and net.sourceforge.squirrel_sql.plugins.dbcopy.CopyExecutor do not have a common superclass |
