The members visibility forced by inline methods always been a pain in the ass for me, specially working on libs, when you want to keep something hidden to the users. Actually I got a

ServiceBuilder

which I would like to keep private, but that doesn’t seem possible 😄 so at least I gave him an internal constructor, creating an public external constructor “scoped” with a context.

Untitled.kt

Am I missing any prettier solution to that? 😄

Hi all

Is there any kotlin extension for spring data common QBE(Query by Example)? QBE must instance class and filter null or not null

What is the proper generic type for this interface in Kotlin?

If I want to have a ResourceManager as a parameter of a function

got the documentation is great.

is anyone know how to declare a varible of type this instance in kotlin ?

hi, why does

listOf("b", "a").toSortedSet()

return [“a”, “b”]

https://twitter.com/kotlin/status/1230530060920217603 You can use the 'takeIf' or 'takeUnless' function, followed by '?.let', in the middle of a call chain to continue execution only under a given condition. #KotlinTips https://t.co/ieEBpxUQ7C Twitter

Hey! should this code work and be thread-safe and deadlock-free? I have a feeling it's causing a deadlock, but i cannot see how it could

class SingleSlotCache<K, V> {
    @Volatile
    private var cacheData: Pair<K, V>? = null

    @Synchronized
    fun getValueBy(key: K, f: () -> V): V = cacheData
        ?.takeIf { (cachedKey, _) -> cachedKey == key }?.second
        ?: f().also { cacheData = Pair(key, it) }
}

as the whole function is synchronized, if one thread is currently accessing the value (and maybe calculating and writing it, because the key doesn't match) the next one to access it should have to wait, and then afterwards just use the value from the first thread (as long as the keys match), shouldn't they? Or am I missing something obvious in how

@Synchronized

works or something...

Right now I would have to recommend excluding Kotlin - as nice a language as it is - as unusable just because of the editing performance issues

well.... IntelliJ performance is abysmal no matter what language you use. there is a "power safe mode" (

File

->

Power safe mode

) that you could try tough

otherwise,... maybe try VSCode, I've heard that the kotlin extension is usable as well.

I'm not super-inclined to bet the farm on VSCode with an abandoned LSP for Kotlin

Having said that, VSCode + Metals (Scala LSP) + Scala is quite zippy, even if it is a little idiosyncratic once in awhile

try the low-power mode, while it turns off most IDE-features it does drastically reduce overhead. you can also try deactivating / uninstalling all plugins you're not using and maybe deactivate some other IDE-features. but IntelliJ being a resource hog is not a kotlin problem, it's a "I'm the most feature-rich IDE on this planet, and I'm written in Java" problem

I really just want intellisense completion, not analysis, so I'll give it a shot. Thanks for the tip

It really depends on your Hardware, though. I don't have problems no matter what, while other's i know have to wait around 10 minutes for IJ to start, and then have to plan every click they do outside the editor in advance or they'll have wasted a few seconds of waiting for IJ to catch up...

after wsimport is there a way to change default http client with ktor http client?

Is it an anti-pattern in Kotlin to use abstract classes with skeleton implementations and some abstract template methods for instance? I mean what are the advantages/disadvantages in contrast to a class which uses higher order functions to provide different behavior?
