org.teiid.query.sql.visitor.StaticSymbolMappingVisitor

This class is used to update LanguageObjects by replacing the virtual elements/ groups present in them with their physical counterparts. It is currently used only to visit Insert/Delete/Update objects and parts of those objects.

        // Get old elements and groups
        List oldSymbols = (List) ElementCollectorVisitor.getElements(obj, false);
        GroupCollectorVisitor.getGroups(obj, oldSymbols);
        
        // Run symbol mapper
        StaticSymbolMappingVisitor visitor = new StaticSymbolMappingVisitor(symbolMap);
        DeepPreOrderNavigator.doVisit(obj, visitor);
        
        // Get new elements and groups
        List newSymbols = (List) ElementCollectorVisitor.getElements(obj, false);
        GroupCollectorVisitor.getGroups(obj, newSymbols);
