Is it possible to choose a

Serializer

to handle a

JsonObject

? I would like to achieve

String

->

JsonObject

-> Logic with

when

statement ->

*MyChosenClass*

. Thank you.

What type is the property in your model?

MyChosenClass

? or

JsonObject

? It sounds like you're describing a normal delegating

KSerializer<MyChosenClass>

where the delegate is

JsonObject.serializer()

MyChosenClass

is the property I'm trying to get to after evaluating a

typeId

from its wrapper class. So

@Serializable(WrapperSerializer::class)
data class Wrapper(
    val typeId: Long,
    val myChosenClass: MyChosenClass,
)

The logic I mentioned is occurring inside the

WrapperSerializer

. I can get the

JsonObject

just fine, it's just after I've identified which serializer to use, I'm not sure how to apply it to a

JsonObject

JsonContentPolymorphicSerializer

may be what you are looking for https://kotlinlang.org/api/kotlinx.serialization/kotlinx-serialization-json/kotlinx.serialization.json/-json-content-polymorphic-serializer/

Maybe, I'm looking into that right now and have used it before, but maybe I just need to readjust my thinking. As for what the path I was going down, I was trying to achieve this inside the serializer.

when(typeId) {
    1 -> Wrapper(typeId = typeId, myChosenClass = decoder.decode(MyChosenClass.Subclass1.serializer(jsonObject)))
}

You don't want to use the

Decoder

because you're not reading from the original JSON but from a model object

I think I see what you're saying. Will I have to manually bind the properties from

jsonObject

into my chosen subclass though? I was trying to avoid that since there's quite a few subclasses and I just wanted to select the serializer from the

typeId

.

That call will give you back an instance of your chosen subclass

Gotcha, I was able to get this moving. Thanks a ton to both of you
