AcyclicVisitor

An interesting read, that seems mainly relevent to the C++ crowd. In Java (and especially dynamically compiled environments like VisualAge) the forces of the pattern do not seem that compelling. Changing the visitor class to accept a new object is not so horrible. Furthermore this pattern introduces more classes that you need to understand. Of course if you do have the problem with header files, then it all makes sense. TimM

Thanks for putting that in Tim, I forgot :( --ta
