Reactive Extensions for the JVM
Java VM implementation of Reactive Extensions: a library for composing
asynchronous and event-based programs by using observable sequences.
.
It extends the observer pattern to support sequences of data/events and adds
operators that allow you to compose sequences together declaratively while
abstracting away concerns about things like low-level threading,
synchronization, thread-safety and concurrent data structures.
