All Known Subinterfaces:

PrecedenceVisitor

All Known Implementing Classes:

DefaultQueryVisitor, DsqlQueryVisitor

public interface QueryVisitor

Shouldn't implement this interface. Always extend DefaultQueryVisitor

This is a visitor interface for go over the DsqlQuery structure and easily translate it to a native one.
