Examples of org.jpox.store.query.Parser

org.jpox.store.query.Parser
Parser for a Query. The query can be JDOQL, or JPQL. Allows a class to work its way through the parsed string, obtaining relevant components with each call, or peeking ahead before deciding what component to parse next. @version $Revision: 1.18 $

        this.toExcl = query.getRangeToExcl();


        // try to determinate fromInclNo and to ExclNo by the range string
        if (query.getRange() != null)
        {
            Parser p = new Parser(query.getRange(), new Imports());


            BigInteger from = p.parseIntegerLiteral();
            if (from != null)
            {
                this.fromIncl = from.longValue();
            }
            p.skipWS();
            if (p.parseChar(','))
            {
                p.skipWS();

                {
                    this.toExcl = to.longValue();
