FunctionalRx

FunctionalRx is a collection of constructs to simplify a functional programming approach to development on Java and Android.

For the RxJava 2.X version please go to FunctionalRx2.

Rationale

The base Java 7 framework does not contain most constructs to do even the simplest functional development. Given that functional programming is a paradigm that's not limited by languages, a series of libraries have been created to bridge some of the gap to others like Kotlin, Scala or Clojure.

FunctionalRx uses RxJava as a backend for their functions and helpers. It's meant to be used in combination with their rective streams.

Usage

An overview of the libraries can be read at Building a Functional Toolset on Android on my blog.

A thorough description and examples of each construct can be found in the readme of their repositories:

RxTuples - Simple tuples to use with RxJava

RxSealedUnions - Tagged Unions for the RxJava aesthete

RxComprehensions - Reduce boilerplate in RxJava by abstracting chained flatMaps, concatMaps and switchMaps

RxActions - Simple ActionN composition to use with RxJava

RxFunctions - Advanced Function composition to use with RxJava

RxCurrying - Simple currying for FuncN and ActionN on RxJava

RxPartialApplication - Simple partial application for FuncN and ActionN on RxJava

RxMemoization - Simple Function result caching for RxJava

Distribution

Each library can be added individually, or as a group by adding FunctionalRx.

Add as a dependency to your build.gradle

repositories {
    ...
    maven { url "https://jitpack.io" }
    ...
}
    
dependencies {
    ...
