The Exception Situation

Log in to save this to your schedule and see who's attending!

Exceptions have been a part of C++ for a long time now, and they are not going away. They allow programmers to concentrate on the meaningful parts of their code and treat the things that happen infrequently as… well, exceptional situations, to be dealt with when and where the context makes it reasonable or useful.

On the other hand, some significant parts of the C++ programming community either dislike this mechanism or outright reject it, for a number of reasons. Work in SG14 has raised performance issues in some cases; there are those who dislike the additional execution paths introduced in programs that rely on exceptions; some programmers raised issues with respect to exceptions and tooling, integration with older codebases, writing robust generic code, etc.

This talk will be neither for not against exceptions. It will present a perspective on cases where they make sense, cases where they are less appropriate, alternative disappointment handling techniques presented along with client code in order to show how the various approaches influence the way code is written. Performance measurements will be given along the way. Some creative uses of exceptions will also be presented in order to spark ideas and discussions in the room.

Professor, Université de Sherbrooke
Patrice Roy has been playing with C++, either professionally, for pleasure or (most of the time) both for over 20 years. After a few years doing R&D and working on military flight simulators, he moved on to academics and has been teaching computer science since 1998. Since 2005, he’s been involved more specifically in helping graduate students and professionals from the fields of real-time systems and game programming develop the skills they... Read More →
