In his great presentation “Inheritance Is The Base Class of Evil,” Sean Parent clearly exposed the flaws of using inheritance and virtual overrides (subclassing) for runtime polymorphism — and solved the bulk of those problems in just 25 minutes. But what if, instead of 25 minutes, he was speaking to a C++ Now audience, with years of experience refining and applying these ideas in production? Could he have gone beyond fixing subclassing flaws — unlocking better performance, greater modeling power, and a universe of new possibilities? Runtime polymorphism via subclassing forces a world of pains: The Busywork: Perfectly great types […]
This presentation is about how Generic Programming Paradigm support in C++ and its portability has enabled us to achieve very good performance and accidentally create a powerful analysis instrument to observe programming technique performance and real "silicon" execution capabilities. We will start by showing how our Hash Tables are "adaptive". We mean by "adaptive" that there are template parameters to modify memory layouts, hashing options, structure organization, and -crucially- bit widths of substructures. Then, at runtime, a table can transform itself into another table with other parameters. We applied the Generic Programming Paradigm from the start, resulting in stunning configurabiity, […]
