[pdg-group] Post Meeting: Visitor

[Abdullah Sowayan]

Hi everyone,

 

During the issue, Nora raised a question about the motivation of having
a visitor in a system. Also, the use of reflection with visitor to solve
some of its limitation was also raised. 

The following article touches on many of these issues. Unlike the GOF
book, this article goes step by step ( starts a small example from
scratch, then tries to extend it, and shows all the resulting mess we
get into) which motivates the need for visitor. 

 

Have a nice weekend,

Abdul
