Hi,

anyone who would know if it's possible to do following in kt syntax ?

[Jiri Bruchanov]

just writing some parametrized test in junit,
and I'd like to do the "lambda2" case in array.
Can I do that somehow directly or via typealias ?

class Object {
    val a: String = "a"
    val b: String = "b"
}

val lambda1 = { v: Object -> v.a }
val lambda2: Object.() -> String = { a }

arrayOf<Any>(
    //lambda1 - works fine
    { v: Object -> v.a },
    //lambda2, how to do this "inlined" - failing, not sure how to tell compiler what type it is
    (Object.() -> String) { a }
)

Are you trying to do something like this?

{ f: Object.() -> String -> Object().f() }

@bsimmons
don't think so,
I need to pass the Object in it, so not totally sure how to do it with your snippet as you create the instance of Object inside of it

[Jiri Bruchanov]

at the end looks like the "nicest" is just property reference like

arrayOf<Any>(
   Object::a
)

Ok
