proxy is an open-source, cross-platform, single-header C++ library, making runtime polymorphism easier to implement and faster, empowered by our breakthrough innovation of Object-oriented Programming (OOP) theory in recent years. Consider three questions: Do you want to facilitate architecture design...

If a function is declared asvirtualin the base class, it will be virtual in all its derived classes. The address of the virtual Function is placed in theVTABLEand the copiler usesVPTR(vpointer) to point to the Virtual Function.
You are able to use many C++ features and not run aground on a lack of the CRT. Simple ADT (Abstract Data Type) classes — those that primarily encapsulate and manipulate resources without using polymorphism — can survive quite nicely, as their methods are simply compiled and linked as norma...
In [20], Parent introduces the notion of non-intrusive value-based runtime-polymorphism, which we will refer to as the runtime concept idiom. Marcus et al. [19,3], and Parent [21] extend this idea, presenting a library that encapsulates common tasks involved in the creation of efficient...
Runtime polymorphism usually connects with v-tables and virtual functions. However, in this blog post, I’ll show you a modern C++ technique that leverages std::variant and std::visit. This C++17 technique might offer not only better performance and value semantics but also interesting design ...
