Is this visitor pattern something that I should care about? I have programmed quite much and never needed it. I found many Java examples from internet and they all were good examples of "over-engineering" IMO. A simple thing made complicated. Virtual methods or method references (kind of event handlers) solve those cases in a cleaner way. Guess I need to study tiOPF finally. It is on my ToDo list anyway.
