Hello everyone, I'm using RxSwift in my iOS app and now I want to use RxKotlin in my Android app, but one question, with RxSwift you can create a Variable to access to the current value (myVar.value) and if you want you can create an observable (myVar.toObservable). There is a way to do that with RxKotlin ?

[gildor]

RxKotlin is just collection of extensions and builders for RxJava - https://github.com/ReactiveX/RxJava

Don’t understand your question tho, maybe you clarify it with example

[gildor]

http://reactivex.io/ - also you can try to find examples of different operators for different Reactive extensions, including RxSwift

I think you mean BehaviorSubject.createDefault(myVar)

RxJava does not have such thing as Variable, the similar thing should be BehaviorSubject

[Pierrick]

With RxSwift we have :

• BehaviorSubject: Starts with an initial value and replays it or the latest element to new subscribers.
• Variable: Wraps a BehaviorSubject, preserves its current value as state, and replays only the latest/initial value to new subscribers.

Maybe it doesn't exist for RxJava/RxKotlin.

Variable does not exist in RxJava/Kotlin, but BehaaviorSubject just lacks the ability to replay the initial value?
I can't think of any case that you need the initial value when you have a more updated value...

[Pierrick]

Yes you can replay the value with the BehaaviorSubject.

But Variable is useful in some case because :
- You can't emit error.
- You don't use onNext.
- You set directly the value property.
- Automatically complete when it’s about to be deallocated.

I can do the job with the BehaviourSubject.

Thank you for your help !
