extract[A](implicit formats: Formats, mf: Manifest[A]): A
Extract a value from a JSON.
Extract a value from a JSON.
Value can be:
- case class
- primitive (String, Boolean, Date, etc.)
- supported collection type (List, Seq, Map[String, _], Set)
- any type which has a configured custom deserializer
Example:
case class Person(name: String) JObject(JField("name", JString("joe")) :: Nil).extract[Person] == Person("joe") -
def
extractOpt[A](implicit formats: Formats, mf: Manifest[A]): Option[A]
Extract a value from a JSON.
Extract a value from a JSON.
Value can be:

- primitive (String, Boolean, Date, etc.)
- supported collection type (List, Seq, Map[String, _], Set)
- any type which has a configured custom deserializer
Example:
case class Person(name: String) JObject(JField("name", JString("joe")) :: Nil).extractOpt[Person] == Some(Person("joe")) -
def
extractOrElse[A](default: ⇒ A)(implicit formats: Formats, mf: Manifest[A]): A
Extract a value from a JSON using a default value.
Extract a value from a JSON using a default value.
Value can be:
- case class
