05/20/2017, 5:11 PM@argoneus depends if the function is inline or not - j

05/20/2017, 5:14 PM@igoticecream I guess that would hurt readability ? - i
igoticecream
05/20/2017, 5:14 PMmake it optional - i
igoticecream
05/20/2017, 5:15 PMYou can either put the return type or let the compiler infer it - j
janvladimirmostert
05/20/2017, 5:17 PM@igoticecream that would make it difficult to see if a function returns Nothing or Something Also, doing something like this:Copy code
and you forget to return something in the lambda, you could potentially be returning the wrong type and not even notice it otherwise I can think of interfaces where having a return type is is mandatory, so making functions not use them is kinda inconsistentreturn (blah) { } - j

05/20/2017, 5:19 PM@igoticecream I made a suggestion in language suggestions that reified should imply that a function is inline, apparently important things in Kotlin are written out explicitly like inline, return types, etc - i

and<in R>
for quite a while, only because IntelliJ suggests using it. what are the benefits of marking generics as in / out other than tightening the abstraction ?<out S> - t

oncontains(element: T?)
? I can't find the code that allows this but the compiler doesn't complain.Iterable<T> - s

is defined in all (usually just one) configurations of your layout file, then yes, it will not be null (except beforerefresh_servers

05/21/2017, 7:43 PMHi, Here's my java interfaceCopy code
I can implement it in kotlin like thispublic interface JavaInterface { String getId(); }Copy code
However, that seems too verbose. So I created a Kotlin interface.class KotlinFromJava(private val id: String) : JavaInterface { override fun getId() = id }Copy code
Now I can do this.interface KotlinInterface : JavaInterface { val id1: String override fun getId() = id1 }Copy code
Is there a way to writeclass KotlinFromKotlin(override val id1: String) : KotlinInterface
without renaming the field?KotlinInterface - d

05/21/2017, 7:49 PMIt would be a lot easier to just turn
into a Kotlin interface.JavaInterface - d
