Should I be using completableFuture in kotlin or is there an alternative. For example I use it here https://github.com/YDWK/YDE/blob/main/src/main/kotlin/io/github/ydwk/yde/rest/action/RestExecutableRestAction.kt#L28 which is then use for methods such as https://github.com/YDWK/YDE/blob/main/src/main/kotlin/io/github/ydwk/yde/rest/methods/UserRestAPIMethods.kt#L33

I don't think

: CompletionStage<T> by CompletableFuture()

does what you think it does. You're making

RestExecutableRestAction

implement

CompletionStage<T>

by delegating all the implementations to a new instance of

CompletableFuture

that has nothing to do with the

completableFuture

property.

Can you give me an example please

Also, your actions hierarchy here is kinda broken because you're not using the same instance of

CompletableFuture

within the same action. For instance

RestExecutableRestAction

provides accessors for its own

completableFuture

property, and it extends

ExtendableAction

which has a separate

completableFuture

property. Using

complete

on

RestExecutableRestAction

will not complete the same future and will have no effect on the

execute

functions. All in all, the whole hierarchy doesn't seem necessary at all. Why not use

CompletableFuture

directly in your case instead of this custom hierarchy?

Ok
