I have a java method written as such

static Function1<MyManager, String> doTheManaging(){
    return MyManager::condense;
}

The kotlin converter can't seem to convert this. Can anyone point me in the right direction?

Converter gives me a new companion object

then

fun doTheManaging(): Function1<MyManager, String> {
 return { valueMap: Map<String, Any> -> condense(valueMap)}
}

but the entire return statement is red

[nanodeath]

try putting Function1<MyManager, String> right after the return

[nanodeath]

also...Map<String, Any> != MyManager.

[nanodeath]

also if Function1 here is Kotlin's own Function1, you can just say (MyManager) -> String instead.

[Colton Idle]

@nanodeath so if I'm understanding correctly, would you say that this is the correct conversion?

fun doTheManaging(): Function1<MyManager, String> {
 return { valueMap: MyManager -> valueMap.condense()}
}

[nanodeath]

assuming condense() returns a String...should work. what is Function1 exactly?

[Colton Idle]

Sorry for asking this seemingly trivial question. Just the whole function stuff is a bit confusing to me.

I always use the converter and never had these types of issues before.

[Colton Idle]

condense does return a string!

[nanodeath]

the best thing might be actually

fun doTheManaging(valueMap: MyManager): String = valueMap.condense()

and then use a method reference

[nanodeath]

but if a method reference isn't possible,

fun doTheManaging(): (MyManager) -> String =
    { valueMap: MyManager -> valueMap.condense }

should also do it, but...it admittedly a little weirder.

Okay. Thanks so much for your help. I think this is starting to make sense now.

👍

the converter is usually pretty good, but...yeah, seems like it failed hard this time.
