Compile Time Constants Part 2: Compile Time Calculations
I have written about what we need compile time constants for last week. This time I will dig a bit into where we can get compile time constants from, and […]
Compile Time Constants Part 1: Why We Need Them
Compile time constants are an important part of C++. They contribute to program correctness and allow the optimizer to do a better job. Today I will deal with what is possible […]
Clean Documentation
“Is there some documentation how I have to configure my IDE to integrate and debug those components?” – “Yes. Have a look at the Wiki. Or maybe there is some […]

Development Environment: Make the Setup Simple
You may be working on a small open source project or on a large corporate team. In either case you will probably have new team members coming in the future. […]
Covariance with Smart Pointers
Covariance can be a useful concept, e.g. when implementing the abstract factory design pattern. However, in modern C++, we should return smart pointers that are not recognized to be covariant like […]
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 […]
Visitor Pattern Part 1- the Object Oriented Way
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 […]
Enum vs. Class Hierarchies
When an enum controls the behavior of a class, that behavior can sometimes be expressed by class hierarchies.
