Overview of the rationale behind cyclops-react and some of it's features, including extended Java Collections, more powerful Sequential and Parallel Streaming, pattern matching, data types (such as Xor cyclops-react Either type, Maybe, Eval).

1. Supercharged
Java 8

2. “
Create a platform that offers the
power as Scala, but as easy to
use as Java.

3. “
Extend the JDK
Reuse JDK Interfaces
Support reactive-streams
Build cross-library abstractions

4. 1
reactive-streams
A standard for interoperability

5. “
Provides a mechanism for
integrating data publishers and
subscribers.
All cyclops-react data structures
support reactive-streams.

6. Cross Project
Example

7. 2
Collection
Extensions
Extend the JDK

8. “
Provide a more powerful stream-
like interface into Java
Collections.

9. Transform a Java
List

10. Transform ListX

11. Group a SetX

12. Schedule Work

13. 3
Persistent
Collection
Extensions
Extend the JDK & pCollections

14. “
Persistent collections are efficient
immutable collections. New
versions are created with plus /
minus ops.

15. Add to a List
(and some other stuff)

16. Remove from a
List

17. 4
ReactiveSeq
Extend the JDK,
support reactive-streams

18. “
A powerful engine for
sequential Streaming.
Implements reactive-streams,
supports asynchronous
streaming.

19. ForEachX

20. Generator
sequence

21. 5
Stream Source
Extend the JDK,
support reactive-streams

22. “
An engine for pushing data into
Streams.

23. Pushing to a
Stream

24. 6
FutureStreams
Extend the JDK,
support reactive-streams

25. “
Asynchronous streaming -
perfect for I/O.

26. Concurrent I/O

27. Why?

28. 7
Data Types
More power to your elbow

29. Eval
Lazy or immediate evaluation
Tail recursive

30. Maybe
Lazy evaluation
Tail recursive
Applicative or monad

31. XoreXclusive Or
Useful for validation

32. 8
Pattern Matching
Exhaustive option checking

33. “
Objects have a composition
structure (an algebra!)
Pattern matching occurs against
that structure.

34. Visitor

35. Matchables

36. Predicates

37. 9
Transformers
Robots in disguise!

38. “
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.

39. Nested List

40. ListT
