Can anyone explain what is reified I'm unable to understand the concept behind this one

[karelpeeters]

Look at the example here: https://kotlinlang.org/docs/reference/inline-functions.html

[kartikpatodi]

ok so is it just syntax sugar and does the same reflection behind the scenes so we dont have to see the ugly code? @karelpeeters

[karelpeeters]

It doesn't do reflection at all, since it is always inline it can inline the type parameter in things like foo is T as well. But yes, the purpose is to hide avoid ugly reflection code.

[kartikpatodi]

got it thanks

@karelpeeters can o tell why this example provided in the docs throwing exception

inline fun <reified T> membersOf() = T::class.members

fun main(s: Array<String>) {
    println(membersOf<StringBuilder>().joinToString("\n"))
}

[karelpeeters]

I can't test right now (not at a computer), does it work directly, ie. without reified funtion calls?

[kartikpatodi]

It works in the IDE but throws error in try.kotlinlang.org

[karelpeeters]

Then there's probably something wrong with the site.

I guess and also they must provide an option to try the beta releases online
Like an option btw stable and beta
