Examples of org.teiid.query.sql.LanguageObject

org.teiid.query.sql.LanguageObject
This is the primary interface for all language objects. It extends a few key interfaces and adds some additional methods to allow the {@link LanguageVisitor}to work.

        return (Criteria)convertObject(simpleCrit, rootNode, metadata);
    }


    public static LanguageObject convertObject(LanguageObject object, MappingDocument rootNode, QueryMetadataInterface metadata)
    throws QueryPlannerException, TeiidComponentException{
        LanguageObject copy = (LanguageObject)object.clone();


        //Don't want to do deep visiting
        XMLNodeMappingVisitor mappingVisitor = new XMLNodeMappingVisitor(rootNode, metadata);
        try {
            PreOrderNavigator.doVisit(copy, mappingVisitor);
