Guidelines for constructor and cast design

by Jonathan Müller

From the article:

A while back — but sadly not too many blog posts ago — I wrote about explicit constructors and how to handle assignment. In this blog post, I made the assumption that you most likely want to have explicit single argument constructors.

But when do we actually want implicit single argument constructors?

Let’s consider the broader question: How should I design a cast operation for my user-defined type? And how should I design a constructor?

But first, something different: what is the difference between a cast and a constructor?

by Krzysztof Ostrowski
