Examples of org.teiid.query.processor.xml.DefaultCondition

org.teiid.query.processor.xml.DefaultCondition
This condition always evaluates to true, basically is a holder for a {@link Program sub Program}, and can therefore be used as the default choice in an {@link IfInstruction IfInstruction}.

        IfInstruction ifInst = new IfInstruction();        
        // if an exception should be thrown as the default choice, then add a sub program to that
        if (choice.throwExceptionOnDefault()) {
            Program subProgram = new Program();
            subProgram.addInstruction(new AbortProcessingInstruction());
            DefaultCondition defCondition = new DefaultCondition(subProgram);
            ifInst.setDefaultCondition(defCondition);            
        }
        
        // to be used by the criteria nodes.
        context.put(choice, ifInst);

            DefaultCondition defCondition = new DefaultCondition(childProgram);
