C++ Design Patterns - The Most Common Misconceptions (2 of N) - Klaus Iglberger - CppCon 2024

https://cppcon.org​ --- C++ Design Patterns - The Most Common Misconceptions (2 of N) - Klaus Iglberger - CppCon 2024 --- Design patterns are everywhere, as they are the key to managing dependencies between software entities. But despite their fundamental importance, there are some common misconceptions about them, in particular about several of the most often used design patterns: * The modern form of the Visitor design pattern, std::variant, is often considered a replacement of virtual functions * The Decorator design pattern is sometimes mistaken as the Adapter design pattern * The Chain of Responsibility design pattern is often confused with Decorators * Explicit object parameters (“deducing this”) is often considered as a modern, better form of CRTP In this talk I'll shed some light on these misconceptions and explain how to properly distinguish between the different design patterns. --- Slides: https://github.com/CppCon/CppCon2024/blob/main/Presentations/Design_Patterns.pdf Sponsored by JetBrains: https://www.jetbrains.com/clion/ --- Klaus Iglberger Klaus Iglberger is a freelancing C++ trainer and consultant and is currently on the payroll of Siemens in Nuremberg, Germany. He has finished his PhD in computer science in 2010 and since then is focused on large-scale C++ software design. He shares his experience in popular advanced C++ courses around the world (mainly in Germany, but also the EU and US). Additionally, he is the initiator and lead designer of the Blaze C++ math library (https://bitbucket.org/blaze-lib/blaze/src/master/) and the organizer of the Munich C++ user group (https://www.meetup.com/MUCplusplus/). --- CppCon is the annual, week-long face-to-face gathering for the entire C++ community. The conference is organized by the C++ community for the community. You will enjoy inspirational talks and a friendly atmosphere designed to help attendees learn from each other, meet interesting people, and generally have a stimulating experience. Taking place this year in Aurora, Colorado, near the Denver airport, and including multiple diverse tracks, the conference will appeal to anyone from C++ novices to experts.
