/**
 * An adapter for the {@link RSQLVisitor} interface that delegates handling of
 * all the concrete nodes to {@link #visit(LogicalNode, Object)} and
 * {@link #visit(ComparisonNode, Object)}.
 *
 * This class is useful when you don't want to handle all of the nodes (i.e.
 * implement visit() methods), but just few of them and take care of
 * the rest in the superclass nodes' handler.
 *
 * @param  Return type of the visitor's method.
 * @param  Type of an optional parameter passed to the visitor's method.
