public interface ExpressionVisitor

Visitor interface for Expression and its derived types.

You may want to use ExpressionVisitorXXXX class if you want to return boolean, void, or Expression.

It is the callee's responsibility to traverse child expression. Expression and its derived classes do not provide any traversal. See ExpressionCloner for example.

onRef method is called for all subclass of ReferenceExp. So you can safely use this interface to visit AGMs from RELAX grammar.
