How do I use the Main dispatcher if my platform isn't Android?

What's your UI framework?

c

camdenorrb

02/17/2019, 3:59 PM

I'm not using a UI

e

elizarov

02/17/2019, 3:59 PM

Then you don't have Main dispatcher.

(nor need one)

:C

Concurrent modification issues tho

Don't share mutable state. No issues

(don't make mistake UI frameworks do)

I'm just adding something to my eventbus

e

elizarov

02/17/2019, 4:01 PM

Isn't your eventbus thread-safe?

c

camdenorrb

02/17/2019, 4:01 PM

Ummmm, not currently lol

e

elizarov

02/17/2019, 4:01 PM

That's a bad event bus

Reading this might give you some ideas: http://kotlinlang.org/docs/reference/coroutines/shared-mutable-state-and-concurrency.html

Thank you :3

Unfortunately after giving it a read, I don't think it helped me very much idea wise. The only thing I got that seems useful is Mutex for the situation I have run in. Anything else I can read @elizarov?

It really depends on what you are trying to achieve

I want to add multithreading/coroutine support to my eventbus

Which at the moment, just seems to be an issue with concurrently adding a value to the list

e

elizarov

02/17/2019, 4:44 PM

You might want to learn more about concurrency, first. "Java Concurrency in Practice" is a good book I can recommend.

c

camdenorrb

02/17/2019, 4:45 PM

Alright

As for coroutines, the easiest thing (that would not require any sharing of mutable state) is to represent your eventbus as an actor, that is confine all its operations to a single coroutine.

c

camdenorrb

02/17/2019, 4:46 PM

Ooo, alright. I'll read up on actors :3

@elizarov Do you suggest using actor coroutines as the event bus for a multiplatform application?
