Interface SqlExprVisitor<T>

Type Parameters:

T -

public interface SqlExprVisitor<T>

A visitor interface (actually just a dummy) However, I don't like this. We usually just need to know whether something is a function, columnRef or literal So for this we hardly need a full blown visitor for all possible leaf nodes
