If I have an extension function that takes in (T) -> Unit as a function type, how can I call this from Java? Does anyone have a code sample of this?

[Shawn]

(T) -> null? What type is null supposed to be here?

[adam-mcneilly]

Flowable<T>.customSubscribeMethod(onNext: (T) -> Unit) sorry misstyped null will edit

[adam-mcneilly]

So I wanna do RxUtilsKt.customSubscribeMethod(myFlowable, ???)

[Shawn]

ahh gotcha

[Shawn]

isn’t that just a Consumer<T> or am I misunderstanding you?

[Ruckus]

You would call it like any other lambda from Java (though you may have to return Unit.INSTANCE)

[Ruckus]

You should be able to do
RxUtilsKt.customSubscribeMethod(myFlowable, it -> { ... })

[adam-mcneilly]

Hmm okay that's close but I'm getting incompatible parameter types

[adam-mcneilly]

RxUtilsKt.doAfterDelay(Flowable.just(1), input -> Unit.INSTANCE);

[Shawn]

what does it say it’s expecting?

[adam-mcneilly]

The error doesn't say

[adam-mcneilly]

got it

[adam-mcneilly]

it was expecting a Kotlin Funciton0<> and when I wrote that the IDE let me rewrite as a lambda

[adam-mcneilly]

RxUtilsKt.doAfterDelay(Flowable.just(1), 100, () -> Unit.INSTANCE);

[adam-mcneilly]

Thanks! 🙂

[Shawn]

Ahh good call @Ruckus

[adam-mcneilly]

In hindsight, I should have just told my coworker to convert the class to Kotlin and we wouldn't stress LOL

[adam-mcneilly]

Also @Ruckus Your snippet was right, I realize I messed with you by having one example of (T) -> Unit and one of () -> Unit I apologize for the inconsistency. 🙂

Sometimes dumbing down your problems causes more trouble than it's worth, should have just posted the actual code haha.
