An advanced, but easy to use, platform for writing functional applications in Java 8.

Getting Cyclops X (10)

• The latest version is cyclops:10.4.0

• Stackoverflow tag cyclops-react

• Documentation (work in progress for Cyclops X)

• Integration modules

Tutorial :

• Dysfunctional programming in Java : A functional tutorial

  • Part 1 : Laziness (Covering Supplier & the Eval monad)
  • Part 2 : Immutability (Covering Immutable Objects with Lombok, withers)
  • Part 3 : Functional Composition (Covering method chaining, Streams, ReactiveSeq, Flux from Reactor)
  • Part 4 : No nulls allowed (Covering class design, Optional, eager / lazy / reactive Option types, Mono from Reactor)
  • Part 5 : No exceptions (Covering making illegal states unrepresentable, eager / lazy Either type, Try)
  • Part 6 : No locks or synchronized blocks (Covering Future, Sequence, FutureStreams and reactive-streams)
  • Part 7 : Immutable Collections (Covering Vector, NonEmptyList and reactive processing)
  • Tagless Final in Java
  • A Java long read : Is functional programming worth it?

What's new in Cyclops X (cyclops 10)

• Fast purely functional datastructures (Vector, Seq / List, LazySeq / LazyList, NonEmptyList, HashSet, TreeSet, TrieSet, HashMap, LinkedMap, MultiMap, TreeMap, BankersQueue, LazyString, Discrete Interval Encoded Tree, Zipper, Range, Tree, DifferenceList, HList, Dependent Map )
• Structural Pattern Matching API (deconstruct algebraic product and sum types)
• Improved type safety via the removal of unsafe APIs -- E.g. Unlike Optional, Option has no get method (which could throw a null pointer) -- New data structures do not support operations that would throw exceptions (you can't call head on an empty list for example)
• Eager and Lazy alternatives for most datastructures (Option is eager, Maybe is lazy + reactive)
• Improved naming of types (Function1-8 rather than Fn1-8, Either not Xor)
• Group id is changed to com.oath.cyclops
• Versioning between cyclops-react and cyclops is merged on cyclops versioning scheme (version 10 = Cyclops X)
• Light weight dependencies : reactive-streams API, KindedJ & Agrona
• JVM Polyglot Higher Kinded Types Support with KindedJ
