supercharged java 8 : with cyclops-react

SuperchargedJava 8

“Create a platform that offers the power as Scala, but as easy to use as Java.

“Extend the JDKReuse JDK InterfacesSupport reactive-streamsBuild cross-library abstractions

1reactive-streams

A standard for interoperability

“Provides a mechanism for integrating data publishers and subscribers.All cyclops-react data structures support reactive-streams.

Cross Project Example

2Collection Extensions

Extend the JDK

“Provide a more powerful stream-like interface into Java Collections.

Transform a Java List

Transform ListX

Group a SetX

Schedule Work

3Persistent Collection Extensions

Extend the JDK & pCollections

“Persistent collections are efficient immutable collections. New versions are created with plus / minus ops.

Add to a List

(and some other stuff)

Remove from a List

4ReactiveSeq

Extend the JDK, support reactive-streams

“A powerful engine for sequential Streaming. Implements reactive-streams, supports asynchronous streaming.

ForEachX

Generator sequence

5Stream Source

Extend the JDK, support reactive-streams

“An engine for pushing data into Streams.

Pushing to a Stream

6FutureStreams

Extend the JDK, support reactive-streams

“Asynchronous streaming - perfect for I/O.

Concurrent I/O

Why?

7Data Types

More power to your elbow

EvalLazy or immediate evaluation

Tail recursive

MaybeLazy evaluation

Tail recursive

Applicative or monad

XoreXclusive Or

Useful for validation

8Pattern

Matching

Exhaustive option checking

“Objects have a composition structure (an algebra!)Pattern matching occurs against that structure.

Visitor

Matchables

Predicates

9Transformers

Robots in disguise!

“Transformers allow nested objects to be manipulated.E.g. A stream of lists can be manipulated by a List Transformer as if it were just a single List.

Nested List

ListT
