Double Dispatch : Visitor Design Pattern in Modern C++
In software engineering, Behavioural Design Patterns deal with the assignment of responsibilities between objects. That in turn, make the interaction between the objects easy & loosely coupled. In this article of the design pattern series, we’re going to take a look at Visitor Design Pattern in Modern C++ which is also known as a classic technique for recovering lost type information(using Double Dispatch[TODO]). Visitor Design Pattern is used to perform an operation on a group of similar kind of objects or hierarchy....
