public interface QueryModelVisitor<X extends Exception>
An interface for query model visitors, implementing the Visitor pattern. Core query model nodes will call their type-specific method when QueryModelNode.visit(QueryModelVisitor) is called. The method meetOther(QueryModelNode) is provided as a hook for foreign query model nodes.
