Precondition Violations (4)
Row |
Violation |
1 | Type net.sourceforge.squirrel_sql.plugins.dbcopy.event.CopyTableListener of variable listener does not match with type net.sourceforge.squirrel_sql.client.session.mainpanel.objecttree.INodeExpander of variable value |
2 | Type net.sourceforge.squirrel_sql.plugins.dbcopy.event.CopyTableListener of variable listener does not match with type net.sourceforge.squirrel_sql.client.session.mainpanel.objecttree.INodeExpander of variable value |
3 | Type java.util.ArrayList<net.sourceforge.squirrel_sql.plugins.dbcopy.event.CopyTableListener> of variable listeners does not match with type java.util.List<net.sourceforge.squirrel_sql.client.session.mainpanel.objecttree.INodeExpander> of variable _expanders |
4 | The refactoring of the clones is infeasible, because classes net.sourceforge.squirrel_sql.plugins.dbcopy.CopyExecutor and net.sourceforge.squirrel_sql.client.session.mainpanel.objecttree.ObjectTreeNode do not have a common superclass |
