RHub - Reactive Event Hub

JavaDocs

Build Status Android Arsenal

Reactive Hub is a collection of multi-receiver and multi-producer Proxies connecting Publishers and Subscribers so that Subscribers can receive events without knowledge of which Publishers, if any, there are, while maintaining easily identifiable connection between them.

It is ideal for centralizing cross-cutting activities like UI updates, logging, alerting, monitoring, security, etc.

Motivation

Example

    RxHub rxHub = new DefaultRxJava1Hub();
    rxHub.getPub("src1").subscribe(System.out::println);
    rxHub.addUpstream("src1", Observable.just(1));
    rxHub.addUpstream("src1", Observable.just(5));
    rxHub.getPub("src1").subscribe(System.err::println);

Overview

RHub

RHub allows Publish/Subscribe pattern implementation and thus helps decouple components. This can be compared to an EventBus where:

In RHub different set of events are separated into Proxies identified by a Tag(topic).
