Precondition Violations (4)
Row |
Violation |
1 | Type net.sourceforge.squirrel_sql.fw.datasetviewer.IDataSetModel of variable src does not match with type net.sourceforge.squirrel_sql.plugins.sqlval.WebServiceSession of variable info |
2 | Unmatched statement return src; cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
3 | Unmatched return src; |
4 | The refactoring of the clones is infeasible, because classes net.sourceforge.squirrel_sql.fw.datasetviewer.DataSetModelEvent and net.sourceforge.squirrel_sql.plugins.sqlval.cmd.ValidateSQLCommand do not have a common superclass |
