Examples of LanguageVisitor

org.teiid.query.sql.LanguageVisitor

The LanguageVisitor can be used to visit a LanguageObject as if it were a tree and perform some action on some or all of the language objects that are visited. The LanguageVisitor is extended to create a concrete visitor and some or all of the public visit methods should be overridden to provide the visitor functionality. These public visit methods SHOULD NOT be called directly.

Examples of org.teiid.query.sql.LanguageVisitor

            
            if (!currentNode.getGroups().isEmpty()) {
                continue;
            }
            
            LanguageVisitor visitor = new LanguageVisitor() {      
                public void visit(CompareCriteria compCrit){
                    if (compCrit.getOperator() == CompareCriteria.EQ && checkForInput(compCrit.getLeftExpression()) && !checkForAnyInput(compCrit.getRightExpression())) {
                        addInputNode((Reference)compCrit.getLeftExpression());
                    }
                }
