# ktor

Hello, I’m trying have interoperability with java and Im using the ktor client and which to receive the body of a response but since receive method is an inline reified I cannot call it from java? Is there any other solution?

[André Martins]

I came up with this

suspend fun <T> HttpResponse.receive(`class`: Class<T>): T =
    call.receive(typeInfo(`class`)) as T

@OptIn(ExperimentalStdlibApi::class)
fun <T> typeInfo(`class`: Class<T>): TypeInfo {
    val kClass = Reflection.createKotlinClass(`class`)
    val kType = kClass.createType()
    val reifiedType = kType.javaType
    return typeInfoImpl(reifiedType, kClass, kType)
}

But not sure if I can just create a Kotlin class like that 😛

Somehow it worked ✌️ (still not sure if its the best way tho)

There is also .kotlin extension on Class<T> in Kotlin Std. Can you not rely on this?

I am wondering how you call this from Java? Just by providing a Continuation callback?

[André Martins]

I just wrap it into a mono or call runBlocking

using kotlinx-coroutines-reactor

Can’t seem to find this one o.o is it on kotlin-stdlib-jvm?

I can access it fine 🤔 I don't even need a import for it.

val x: Class<String> = String::class.java
val y: KClass<String> = x.kotlin

I am using implementation("org.jetbrains.kotlin:kotlin-stdlib") with plugin org.jetbrains.kotlin.jvm
