RxBus

Event bus framework supports sticky events and subscribers' priority based on RxJava 3.x

Getting started

This library is distributed by jitpack.

You should add jitpack maven repository to build.gradle file of your project.

repositories {
    ...
    maven { url 'https://jitpack.io' }
    ...
}

Then you can include this library by adding dependency script to build.gradle file of your project.

dependencies {
    ...
    compile 'com.github.ridi:rxbus:<version>'
    ...
}

How to use

Defining event class

class Event(val value: Int) {
    override fun toString() = "{value=$value}"
}

Event subscription/posting

RxBus.asObservable(Event::class.java).subscribe { e ->
    System.out.println(e.toString())
}
RxBus.post(Event(0))

Output

{value=0}

Sticky events

Sticky event

RxBus.postSticky(Event(0))
RxBus.asObservable(Event::class.java, sticky = true).subscribe { e ->
    System.out.println(e.toString())
}
RxBus.post(Event(1))

Output

{value=0}
{value=1}

Subscription priority

RxBus.asObservable(Event::class.java, priority = -1).subscribe { e ->
    System.out.println("-1 Priority : $e")
}
RxBus.asObservable(Event::class.java, priority = 1).subscribe { e ->
    System.out.println("1 Priority : $e")
}
RxBus.asObservable(Event::class.java).subscribe { e ->
    System.out.println("Default(0) Priority : $e")
}
RxBus.post(Event(0))

Output

1 Priority : {value=0}
Default(0) Priority : {value=0}
-1 Priority : {value=0}
