I feel like I’ve seen code like this written

deserialize<PatientDto>(message.payload)

where the called method then gets the class

internal fun <DTO : Any> deserialize( ba: ByteArray, clazz: KClass<DTO> ): DTO {
        return mapper.readValue(ba, clazz.java)
    }

pretty sure it’s in gradle’s kotlin DSL somewhere… how do I replicate that calling signature?

I think you’re looking for Reified Generics https://kotlinlang.org/docs/reference/inline-functions.html#reified-type-parameters

[Pavlo Liapota]

Something like this:

inline fun <reified T> foo() {
    foo(T::class)
}

fun <T> foo(clazz: KClass<T>) {
    
}

[xenoterracide]

does it have to be only that as a parameter?

[xenoterracide]

internal inline fun <reified DTO : Any> deserialize(ba: ByteArray, clazz: Class<DTO> ): DTO {
        return mapper.readValue(ba, clazz)
    }

[xenoterracide]

isn’t showing me any love

[xenoterracide]

the caller says the parameter is missing

[Czar]

you've added an unnecessary param to the signature. Should be:

internal inline fun <reified DTO : Any> deserialize(ba: ByteArray): DTO {
    return mapper.readValue(ba, DTO::class.java)
}
