The Visitor Pattern strikes fear into the hearts of Java programmers. It works well, as long as we do not touch the element hierarchy.

Many derivates of Visitor try to address this deficiency. One of these is the Acyclic Visitor by Uncle Bob, published 20 years ago. One of its challenges is dealing with unexpected elements. Since we are trying to avoid a cyclic dependency, we cannot let Visitor know about Element. We thus should not have a default handler in the Visitor superclass.

In this webinar, we will look at the Acyclic Visitor and compare it to our modern version of the GoF Visitor. We will also look at how we can refactor both versions to use MethodHandle to create a common accept() method.

We invite all readers of The Java Specialists' Newsletter to join us for this special event. A recording of the webinar will be available afterwards.
