Breaking Dependencies - C++ Type Erasure - The Implementation Details - Klaus Iglberger CppCon 2022

Discover the power of C++ type erasure, learn how to decouple interfaces from implementations, and improve code design flexibility and efficiency in this insightful talk.

Key takeaways

The talk discusses the concept of type erasure in C++ and its advantages.
Type erasure is used to decouple the interface of a class from its implementation.
It eliminates the need for inheritance and allows for more flexibility in code design.
The talk introduces the concept of “affordances” which refers to the operations that a class provides.
The speaker explains how type erasure can be used to create a base class that can be extended by any shape class.
The talk discusses the concept of “move operations” and how they can be used to improve the efficiency of code.
The speaker also mentions the importance of using const references to avoid unnecessary copying.
The talk introduces the concept of “small buffer optimization” which is a technique used to improve the efficiency of code by using a small buffer instead of dynamic memory allocation.
The speaker discusses the concept of “ prototypes” which are used to create a base class that can be extended by any shape class.
The talk also mentions the importance of using a proper naming convention to make the code more readable.
The speaker explains how type erasure can be used to create a base class that can be extended by any shape class.
The talk discusses the concept of “value semantics” which refers to the idea that objects should behave like values.
The speaker also mentions the importance of using a proper return type to avoid unnecessary copying.
The talk introduces the concept of “run-time type identification” which is used to determine the type of an object at run-time.
The speaker discusses how type erasure can be used to improve the flexibility of the code.
The talk also mentions the importance of using a proper naming convention to make the code more readable.
The speaker explains how type erasure can be used to create a base class that can be extended by any shape class.
The talk discusses the concept of “polymorphism” which is the ability of an object to take on multiple forms.
The speaker also mentions the importance of using a proper naming convention to make the code more readable.
The talk introduces the concept of “flyweight pattern” which is used to reduce the memory overhead of objects.
The speaker discusses how type erasure can be used to improve the efficiency of the code.
The talk also mentions the importance of using a proper naming convention to make the code more readable.
The speaker explains how type erasure can be used to create a base class that can be extended by any shape class.
The talk discusses the concept of “composite pattern” which is used to combine objects into a single object.
The speaker also mentions the importance of using a proper naming convention to make the code more readable.
The talk introduces the concept of “visitor pattern” which is used to add new behavior to objects.
The speaker discusses how type erasure can be used to improve the flexibility of the code.
The talk also mentions the importance of using a proper naming convention to make the code more readable.
The speaker explains how type erasure can be used to create a base class that can be extended by any shape class.
The talk discusses the concept of “iterator pattern” which is used to create a way to iterate over objects.
The speaker also mentions the importance of using a proper naming convention to make the code more readable.
The talk introduces the concept of “adaptor pattern” which is used to adapt the interface of an object.
