Examples of org.voltdb.planner.BoundPlan

org.voltdb.planner.BoundPlan
BoundPlan is an immutable representation of a SQL execution plan. It refers to a parameterized statement, and so it could apply to multiple SQL literal strings before constants have been pulled out. It also has an array of constant values for any bound parameters, referenced positionally, that are required by the plan. It is an element of the parameterized plan cache.

        assert(new String(plan.sql, Constants.UTF8ENCODING).equals(sql));


        // uncomment this to get some raw stdout cache performance stats every 5s
        //startPeriodicStatsPrinting();


        BoundPlan matched = null;
        BoundPlan unmatched = new BoundPlan(planIn.core, planIn.parameterBindings(extractedLiterals));
        // deal with the parameterized plan cache first
        List<BoundPlan> boundVariants = m_coreCache.get(parsedToken);
        if (boundVariants == null) {
            boundVariants = new ArrayList<BoundPlan>();
            m_coreCache.put(parsedToken, boundVariants);
