org.jboss.dna.graph.query.process.QueryProcessor
An abstract {@link Processor} implementation that builds a tree of {@link ProcessingComponent} objects to perform the differentparts of the query processing logic. Subclasses are required to only implement one method: the {@link #createAccessComponent(QueryCommand,QueryContext,PlanNode,Columns,Analyzer)} should create a ProcessorComponentobject that will perform the (low-level access) query described by the {@link PlanNode plan} given as a parameter.

        return queryEngine;
    }


    protected QueryEngine getQueryEngine( Optimizer optimizer ) {
        Planner planner = new CanonicalPlanner();
        Processor processor = new QueryProcessor() {
