WARNING: it won't be simple
I'm using visitor pattern in my project and to the best of my knowledge,
the visitor should be implemented as an interface.
Why ?
tiOPF uses the visitor pattern extensively, and it is implemented as a
class.
Is this visitor pattern something that I should care about?
I have programmed quite much and never needed it.
You don't need to care about it. It's a pattern like any other.
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.
Well, visitors have their uses, but I wouldn't overstate their usefulness.
Use the right tool for the job, I'd say. :-)
Michael.
