bliki: Tell Dont Ask
Tell-Don't-Ask is a principle that helps people remember that object-orientation is about bundling data with the functions that operate on that data. It reminds us that rather than asking an object for data and acting on that data, we should instead tell an object what to do. This encourages to move behavior into an object to go with the data. Let's clarify with an example. Let's imagine we need t

What methods belong on an entity? - In Relation To
Kinda tangentially related to this discussion, I'm often asked whether I believe in rich domain models or anemic domain models. I guess I'm pretty much ignorant as to what these terms really mean, since I've never seen a proper definition of either term. If by anemic domain model, we mean /never/ writing any business logic on our object model, and if by rich domain model, we mean /writing as much

On the Tension Between Object-Oriented and Generic Programming in C++
The author discusses how the use of generic programming in C++ can lead to conflicts with object-oriented design principles. He demonstrates how a technique known as type erasure can often be used to resolve these conflicts. An in-depth example is presented: any_iterator, a type-safe, heterogeneous C++ iterator. In his glossary of terms[1], Bjarne Stroustrup has described the C++ programming langu
