FC++: Functional tools for object-oriented tasks

Abstract

FC++ is a library for programming functionally in C++. Compared to other C++ functional programming libraries, FC++ is distinguished by its powerful type system which allows the manipulation of parametrically polymorphic functions (e.g., passing them as arguments to other functions and returning them as results). In this paper, we show how FC++ can be used in common object-oriented programming tasks. We demonstrate FC++ implementations of several common design patterns (Adapter, Builder, Command, and more). Compared to conventional C++ implementations of these patterns, our implementations are either simpler (in that fewer classes/dependencies are needed), more efficient, or more type-safe (thanks to parametric polymorphism and type inference).
