Hello <@UHGG4DEHJ>back again with another question...

Hello @Uberto Barbiniback again with another question I can’t figure out.
I got a service that reponds a String:

{ total: "10" }

But I know it is an Int and want to map it in my object as a int

data class Response(val total: Int?)

Can’t figure out how to write the converter to do that ?
I was thinking about something like this but couldn’t make it work.

JResponse : JAny<Response>() {
  private val total by str???

  override fun JsonNodeObject.deserializeOrThrow(): Response = Response(total = (+total)?.toIntOrNull())
}

Looks like what I’m looking for is in the todo part of the readme 😉

TODO: add example of class with private constructor and custom serializer/deserializer

[Razvan]

I managed to come up with something that works using a custom StringRepresentable implementation

object JIntAsString : JStringRepresentable<Int>() {
    override val cons: (String) -> Int = {s: String -> s.toIntOrNull() ?: 0}
    override val render: (Int) -> String = Int::toString
}

object JResponse : JAny<Response>() {
  private val total by JFieldMaybe(Response::total, JIntAsString)

 override fun JsonNodeObject.deserializeOrThrow(): Response = Response(total = +total)
}

Was there a better way ?

I think this is the best way (overriding JStringRepresentable)

You can define a str shortcut function if you have multiple uses

Thank you.
