  4. def as[A](implicit reader: Reader[A]): A

    Given that an implicit reader of type A is in scope It will deserialize the org.json4s.JValue to an object of type A

    Given that an implicit reader of type A is in scope It will deserialize the org.json4s.JValue to an object of type A

    Example:

    case class Person(name: String)
implicit object PersonReader extends Reader[Person] {
  def read(json: JValue): Person = Person((json \ "name").extract[String])
}
JObject(JField("name", JString("Joe")) :: Nil).as[Person]

  6. def getAs[A](implicit reader: Reader[A]): Option[A]

    Given that an implicit reader of type A is in scope It will deserialize the org.json4s.JValue to an object of type Option[A]

    Given that an implicit reader of type A is in scope It will deserialize the org.json4s.JValue to an object of type Option[A]

  def read(json: JValue): Person = Person((json \ "name").extract[String])
}
JObject(JField("name", JString("Joe")) :: Nil).getAs[Person]
  7. def getAsOrElse[A](default: ⇒ A)(implicit reader: Reader[A]): A

    Given that an implicit reader of type A is in scope It will deserialize the org.json4s.JValue to an object of type A if an error occurs it will return the default value.
