toJson

abstract fun toJson(writer: JsonWriter, customScalarAdapters: CustomScalarAdapters, value: T)

Serializes a Kotlin type into its equivalent Json representation.

Example:

override fun toJson(writer: JsonWriter, customScalarAdapters: CustomScalarAdapters, value: LocalDateTime) {
  writer.value(value.toString())
}

Alternatively, you can use the built-in AnyAdapter:

override fun toJson(writer: JsonWriter, customScalarAdapters: CustomScalarAdapters, value: GeoPoint) {
  val map = mapOf("lat" to value.lat, "lon" to value.lon)
  AnyAdapter.toJson(writer, map)
}
