Visitor Pattern Part 2 – the enum based visitor
In my last post I showed the Visitor design pattern in its fully object oriented implementation. In the post before that I wrote about moving from enums to class hierarchies. I […]

If you have read the “Gang of Four” book about design patterns or just have been long enough in software development, you will have heard of the Visitor pattern. In its fully […]
When an enum controls the behavior of a class, that behavior can sometimes be expressed by class hierarchies.
Sometimes, a fixed set of string values is allowed as input. Often these string values are then stored, used for control flow etc. Enumerators are a better alternative.
C++ itself is complex enough. Adding domain specific languages can seem like yet another addition to that complexity. So why would we use a DSL instead of a normal library?
In the last two posts I have written about compiler warnings. There’s much more to getting hints about code smells and potentially problematic pieces of code than that. That’s the job […]
In the last post I wrote about how to change our code to avoid getting compiler warnings. Sometimes that is not a feasible approach and we need to tell your compiler […]
We often see compiler warnings about pieces of code that have potential problems or poor style. Sometimes they point out code that is actually wrong, so don’t ignore them.
This is another post motivated by Twitter: It’s about those cheat sheets, for example those showing C++ operator precedence, that some people have stick to their monitor or cubicle wall. Unless they […]
Have you seen classes with a method isValid() or something similar? You most definitely have seen and even used such classes. Maybe you have even written such a method yourself. […]
