ok - thx for the info

Hey all, I have this extension method:

/**
 * Subscribe to notifications of a certain type, specifying a priority.
 */
inline fun <reified T : Any> Match.subscribe(vararg states: Match.State, priority: Int, noinline notifier: T.() -> Unit) {
    subscribe(StatefulTypedSubscription(this, states, T::class, notifier, priority))
}

However IntellIJ doesn't seem to like me using it

I am just waiting for anko to be compatible with the latest beta plugin

What's up guys...! I'm try learn kotlin first just convert my java class to kotlin than see whats different and practice it. LOL

hello. there supposed to be slack channel for Kotlin contributors, is this the one?

(what do people think about having a channel for library announcements?)

wait, functions that use

reified

will be private from Java? 🤔

inline fun <reified T> findInputValueByHint(hintToFind: String): T? {
		val inputField = inputFields.find { field -> field.hint == hintToFind }
		return inputField?.getInputValue() as? T
	}

can’t be accessed through java code. (although only public members are used)

Error:(91, 35) error: <T>findInputValueByHint(String) has private access in InputGroup
where T is a type-variable:
T extends Object declared in method <T>findInputValueByHint(String)

or am I missing something here?

apparently it’s time to convert the whole code base, then 🙂

anyone have a project using Spring Docs?

Maybe it will become clear as I use Kotlin more, but why is there a "primary" constructor along with the standard way of defining constructors? Is there any significance to primary constructors other than the syntax and the lack of a body? What was the impetus? There are several Kotlin features that just leave me scratching my head

I guess it's just the way to say "this constructor must always be called, one way or another"?

Hello. I'm trying to define a data class that has a ByteArray as a field. I want to do a defensive copy of the array on construction, but I'm not quite sure how to do that, does anyone have a tip?

That way don't I end up with two copies of the data, then? I'm thinking:

data class Thing(private val data: ByteArray) {
val copy = Arrays.copyOf(data, data.size)
}

Even if I use

copy

exclusively, I'm still holding a reference to

data

I guess you can use a factory function then

or don't use a data class and write equals, hashcode, toString

why another language "kotlin" as there are so many are there in the world !!!

@alan.kleiman you don't need to use

val

in the constructor if you don't want to keep a reference to it

@bj0 That's not allowed in a data class.

@abreslav how to fire the alert box in Kotlin for java script there is no mention about it in the docs.

Hey! I’m experiencing

error.NonExistentClass

in generated code with kapt3.

Any idea?

Error log ?

there are no errors (I mean except the fact that the compiler cannot find this class which is normal since it doesn’t exist)

ok I fixed it by adding

kapt {
    correctErrorTypes = true
}

as per the kapt doc 😉

funny how by default the “correct” mode is disabled… 😉

@dnvshp, good question; I'm trying to clarify this in my head because I'm thinking about doing a presentation at work, and I don't want the usual "list of cool features" approach. The main reasons to me are: (1) a cross-ecosystem language (JVM, Android, JS front-/back-end, iOS, and other native) so you can build more of a large system with less need to switch your thinking; (2) a much nicer language to use than Java but highly interoperable in both directions, and easy for Java devs to learn (compared to, say, Scala, Clojure, or Ceylon); and (3) suitable and mature enough for commercial use (but also open source, so less worry that it might disappear) and with great tool support.

Guys, I’m trying to migrate my project from java to kotlin, it uses dropwizard + hibernate. I’m facing this exception

No session currently bound to execution context

when i’m accessing the DAO classes from main app class.
