Jan 7, 2020 · In standard UML, there is no simple way to my knowledge, to represent higher order functions: Higher-order functions are a core feature for functional programming. But in UML an action cannot produce an action that is executed by another flow. It can not either accept actions as input to another action.

Aug 19, 2016 · Functional programmers generally don't have a lot of use for diagrams. Many functional programmers (but not all) find that writing down types is a good way to encapsulate the design relationships that OO programmers put into UML diagrams.

Interaction Diagrams – model the interactions between multiple stateful processes. Clearly, this is not useful for modeling the internals of a pure functional program. However, UML is not only about modelling the structure of code, but primarily about providing an universal modelling language.

Mar 3, 2014 · While the most popular types of UML diagrams are structural, use case and sequence (interaction) IMHO. Functional programs don’t have classes, but they still have the structure, because we can identify logical parts of code and how they *relate* to each other.

Most UML applications today allow reverse engineering of Diagrams from existing code, and Code generation from the Diagrams. This means that you can document legacy code with UML, and use UML during a feature's design phase, from which code can be generated when starting to work on the feature implementation.

Sep 2, 2009 · Sequence diagrams (UML) could be related to the composition of functions. A static class diagram (UML) could be related to type signatures.

Nov 18, 2014 · Does standard UML specify how a variant (aka tagged union, discriminated union, sum type, etc) should be depicted in a class diagram?

With UML diagrams, you need to translate them to code, with the possibility of losing something in translation. But if the design is documented in your programming language itself, there is no translation phase, and so the design must always be in sync with the implementation.

Functional programming languages are ideally suited for developing dependable software, but not much work have been done on modeling functional programs. Although UML is mainly based on concepts which are native to imper-ative object-oriented programming languages, this chapter shows how – through

Jul 31, 2023 · I am just looking for a solid process to visually represent functional process prior to writing functional code. It doesn’t have to be UML. Right now I am working through a course in Model Based Engineering centered around SYSML to see how well it might serve.
