Let us collect few sites here:

Theoretical Help:

(1) http://en.wikipedia.org/wiki/Visitor_pattern - Introduction and Motivation for design and use of visitor patterns is nicely depicted in Wikipedia for Visitor pattern.

(2) http://www.oodesign.com/visitor-pattern.html - One of the top visited sites for design pattern basics to implementation, oodesign.com has good introduction, implementation details.

(3) http://sourcemaking.com/design_patterns/visitor This page has good detailed description of visitor pattern and the worth reading part is the discussion section of this page which also talks about how double dispatch is related to visitor.

(4) http://www.dofactory.com/Patterns/PatternVisitor.aspx - Simple introductory page which describes and talks about the pattern in short.

Java: (1) http://java.dzone.com/articles/design-patterns-visitor (2) http://www.javaworld.com/javatips/jw-javatip98.html (3) http://snehaprashant.blogspot.com/2009/01/visitor-pattern-in-java.html (4) http://en.wikipedia.org/wiki/Visitor_pattern#Java_example

C++: Following are the links which provides examples based on C++: (1) http://sourcemaking.com/design_patterns/visitor/cpp/1

(2) http://sourcemaking.com/design_patterns/visitor/cpp/3

(3) http://sourcemaking.com/design_patterns/visitor/cpp/2

(4) This page explains visitor pattern in detail from the basics upto implementation using C++ as language. It has implementation details and also have discussed issues that arise. http://www.swe.uni-linz.ac.at/research/deco/designPatterns/visitor/visitor.defaultroles.c++.html


Python: Following are two links which provide good examples of implementation of visitor patterns in python: (1) https://chris-lamb.co.uk/2006/12/08/visitor-pattern-in-python/ (2) http://curtis.schlak.com/2012/01/04/python-visitor-pattern-helper.html

Ruby: (1) https://gist.github.com/989193 (2) http://www.scribd.com/doc/2217773/Design-Patterns-in-Ruby


Advantages Discussed: (1) This links helps to understand the advantage of a design pattern like visitor, which are the features it combines and how it makes it easy for programmer to implement those ideas. http://compilers.cs.ucla.edu/jtb/jtb-2003/whyvisitors/whyvisitors.html (2) The applicability of visitor pattern can be found here: http://www.swe.uni-linz.ac.at/research/deco/designPatterns/visitor/visitor.abstract.html#Applicability

Disadvantages: (1) This page has a subsection in the visitor pattern section which discusses issues related to visitor pattern. http://www.developerfusion.com/article/84939/iterators-composites-and-visitors/ (2) http://www.oodesign.com/visitor-pattern.html
