thanks damian! @d.kolakowski

did not know that trick . . .

You can check the output of the compiler by looking at the bytecode window (Tools -> Show Kotlin Bytecode)

also wrong Damian 😉

Please don't do this for performamce reasons ☺️

^^

this is what I love about Kotlin. they can fix things!

the DSL looks nicer but I’ll most likely go with nest constructor invocations where the objects can be immutable

I’m not alone (see comment): https://youtrack.jetbrains.com/issue/KT-6592#comment=27-1448846

inline fun <reified T : Any, M: MetadataHolder> AbstractAutoMetadataCreator<M>.registerClassKt(creator: MetadataCreator<T, M>) = this.registerClass(T::class.java, creator)

Is there a way to get M to be automatically interpreted from the instance

AbstractAutoMetadataCreator

?

Am I doing something wrong, or intellij Idea doesn't mark exceptions as exceptions

?

Can you show us the contents?

@User uploaded a file:

@roamingthings There is the

@Contract

annotation, which would allow you to specify this, but it seems the Kotlin compiler does not honor it.

@karelpeeters commented on @martwy_kotek’s file : That's the only thing in that file? Looks like Idea does indeed not have an exception symbol for Kotlin, you can file an issue if you want.

@karelpeeters ok, thanks

so in Java it will be

public class Login {
    
    @NotBlank
    @Size(min=3)
    private final String login;
    
    @NotBlank
    private final String password;

    public Login(String login, String password) {
        this.login = login.trim();
        this.password = password.trim();
    }

    public String getLogin() {
        return login;
    }

    public String getPassword() {
        return password;
    }
}

I have a class

data class Login(@get:NotBlank @get:Size(min=3) @JsonProperty(value = "login", required = true) val login: String, 
                  @get:NotBlank @JsonProperty(value = "password", required = true) val password: String)

annotations are used for validation, validation is executed after constructor but before validation, I need to trim

login

and

password

, in order to reject values as " r " for

login

, because real value is "r" and size is 1, which is less than 3 how to do this in Kotlin? 1 reply you can try:

class Login(login: String, password: String){
    @get:NotBlank @get:Size(min=3) @JsonProperty(value = "login", required = true) val login: String = login.trim()
    @get:NotBlank @JsonProperty(value = "password", required = true) val password: String = password.trim()
}

in the profiler, I see objects like foo.bar.someclass$someMethod$1, all of those methods create instances of lambdas. are those the closure object containing whatever has been closed over?

or are those something else?

Im having trouble tracking down the source of this issue. Hoping someone here could shine some light on my problem. When I try to compile a simple blink demo I get this error.

Linking globals named 'Konan_start': symbol multiply defined!

Seeing an odd problem the last day or two in one of my projects, I’m using Gradle. I’m not sure what changed that might be causing it. When I do something like rename a function in my main module, and then try to run a unit test, I get build errors suggesting that the refactor didn’t occur, but IntelliJ’s editor is behaving as it did occur (it doesn’t register any error). I’m using Gradle. Anyone have any ideas?

I also get the same errors if I try to build. For some reason it seems like the Kotlin compiler isn’t seeing the refactor, but the IntelliJ editor is…?

I’ve tried doing a gradle reimport

@Ian Have you tried

gradle clean

, and invalidating Idea's caches? (

File > Invalidate ...

)?

Also please don't crosspost like this.

In intellij IDEA, is there anyway to enabled autocomplete of class property names based on available classes?

it works fine for method parameters
