help with understanding the visitor pattern

Oct. 16, 2019

      Hello,

Im busy with this project: https://github.com/RoelofWobben/Die

Now I also want to try to add a DieHandler and a Die together.
And I heared you can use the visitor pattern to solve this.

As far asÂ  I understand the pattern I have to make a new class which 
contains only the + method.

But I fail to understand to see how I can make a difference between the 
+ of a Die and the + of a DieHandler.

So can someone help me understand this pattern and maybe learn me step 
by step how to implement this in my code.

Regards,

Roelof
