12/22/2015, 11:42 AMI think they provide value if they are used as secondary constructors. something likeCopy codeclass Foo(val a: Bar) { <T> constructor(provider: BarProvider<T>, key: T) : this(provider.provide(key)) } - v

12/22/2015, 11:42 AMwhy not a factory method? - k
kirillrakhman
12/22/2015, 11:43 AMbecause a companion object adds boilerplate and putting the factory method outside of the class makes it less cohesive - v
voddan
12/22/2015, 11:44 AMjust a functionFoo() - v
voddan
12/22/2015, 11:45 AMno companion objects - v
voddan
12/22/2015, 11:45 AMsorry - v
voddan
12/22/2015, 11:46 AMi wanted to say that using package-level functions was a proposed solution for working around secondary constructors when they were not in the lang - c
cy
12/22/2015, 11:48 AMand a top-level function is still a good enough workaround for missing generic constructors - k
kirillrakhman
12/22/2015, 11:51 AMsure, there's just the small pain that the file isn't a single-class file anymore and looks different in the project view 😄 - c
cy
12/22/2015, 11:52 AMwell, then use top-level functions more.. so all files will look the same in the project view simple smile - k
kirillrakhman
12/22/2015, 11:52 AMnot sure that's the best way to structure your project. top-level functions have their place, but so do classes - s

12/22/2015, 11:59 AMIn my example, the following does not compile :Copy code
That's because both the function and the constructor have the same signature.fun <T : Any> Test(klass: KClass<T>, value: T) = Test(klass, value) class Test internal constructor(val klass: KClass<*>, val value: Any) { } - s
salomonbrys
12/22/2015, 12:00 PMSo the only way is to name the factory method differently than the class. - s

12/22/2015, 12:01 PMWhich, I believe, breaks the kotlin idiom - k
kirillrakhman
12/22/2015, 12:03 PMor do the companion object thing - c

Didn't it work before?KPropertyN now extend FunctionN, i.e. list.map(String::length) works now - d

this works also in Beta 3Array(10) { it }.map(Int::toString) - e

12/22/2015, 7:45 PMnot that we can convert our project to kotlin but maybe write our tests with it. - u
