Precondition Violations (4)
Row |
Violation |
1 | Type net.sourceforge.squirrel_sql.plugins.dbcopy.gui.PreferencesPanel of variable prefs does not match with type net.sourceforge.squirrel_sql.fw.datasetviewer.IDataSetViewer of variable _viewer |
2 | Unmatched statement _viewer.clear(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
3 | Unmatched statement prefs.applyChanges(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
4 | The refactoring of the clones is infeasible, because the number of macthed statements is equal to zero |
