Hey folks! How can I tell Kotlin that I want a primitive type

float[]

array instead of the boxed

Float[]

array? I want to convert a

FloatArray

using

toTypedArray()

.

At the same time discovered life without Spring, felt like the training wheels came off, but that was a good thing

#server might be a better place

Is it because Array isn't a fully-fledged object at all, and this is Kotlins way of representing the JVM's 'first class' array as close to an object as possible?

what is the best way to share fields in kotlin's "union"? I mean I'd like to automagically share the four fields from the base type here:

sealed class SchedulerMessage<T>(
    val receiver: (T) -> Unit,
    val msg: T,
    val initialDelay: Duration,
    val replayCh: Channel<Job>
)

class Schedule<T>(
    val delayBetween: Duration
) : SchedulerMessage<T>()

class ScheduleOnce<T>() : SchedulerMessage<T>()

but it does not compile.

@vaskir The way that has the least amount of boilerplate seems to be this:

sealed class SchedulerMessage<T> {
    open val receiver: (T) -> Unit
    open val msg: T
    open val initialDelay: Duration
    open val replayCh: Channel<Job>
}

class Schedule<T>(
    override val receiver: (T) -> Unit,
    override val msg: T,
    override val initialDelay: Duration,
    override val replayCh: Channel<Job>,
    override val delayBetween: Duration
) : SchedulerMessage<T>()

class ScheduleOnce<T>(
    override val receiver: (T) -> Unit,
    override val msg: T,
    override val initialDelay: Duration,
    override val replayCh: Channel<Job>
) : SchedulerMessage<T>()

However, I would highly recommend to consider replacing inheritance (“is a”) with delegation (“has a”)

I don't need to access the fields via the base class reference.

I need "extendable record"

so I have this:

sealed class SchedulerMessage<T>

class Schedule<T>(
    val receiver: (T) -> Unit,
    val msg: T,
    val initialDelay: Duration,
    val delayBetween: Duration,
    val replayCh: Channel<Job>
) : SchedulerMessage<T>()

class ScheduleOnce<T>(
    val receiver: (T) -> Unit,
    val msg: T,
    val initialDelay: Duration,
    val replayCh: Channel<Job>
) : SchedulerMessage<T>()

it's ok, but the fields are duplicated

Create a separate class for the four fields you share, but don’t extend it, just use it.

so extract the fields to a new class?

🙂

ok

but it's kind of manual work. I think Nemerle allows to define "shared" fields.

oh it means it’s fixed I guess 🙂

Is there an IRC bot framework designed around idiomatic Kotlin?

I know pircbotx exists, but that's more meant for java

i don't know of one. i just use pircbotx.

but then my bot was converted from java

Hi everyone, pleasure to be posting to the group and learning kotlin

I am working on a vertx.io based web server

using kotlin, gradle-script-kotlin

I finally may have found a reason to move over to KotlinTest or Spek

of course that's also a solution 😄

kotlin promises good java interop, not groovy 😄

I just really like spock, so would like to find a way
