Would the

getProperty

function in this case be best declared

inline

?

fun main() {
    val someHashMap = mapOf("first" to Account1("test", "1234"))
    println(getProperty("first") {someHashMap.getValue(it).number})
}

fun getProperty(name: String, action: (String) -> String) : String{
    return action(name)
}

class Account1(val name: String, val number: String)

I checked the decompiled Java bytecode but I can't work out why inline is better? Is it because in the

none-inline

it calls the

getProperty

function in the

main

like in here? https://gist.github.com/rinnegan/4233b6a242b5f2864e0737b186b45df7#file-inline-vs-none-inline-L33

In the non-inline one there's an instance of

Function

created for every call, in the inline one that isn't necessary.

ah did you mean this call

(Function1)(new Function1()

?

Yes, that's what I mean. You're welcome!
