trait Extract[T] extends AnyRef

Lets you pattern match JsValues to T.

For example,

case class Foo(field: Int)

object Foo {
  implicit val format: OFormat[Foo] = Json.format[Foo]
  object Extract extends JsonFormats.Extract[Foo]
}

val Foo.Extract(foo) = Json.parse("""{"field": 2}""")

def caseClassFormat[T, S](apply: (S) ⇒ T, unapply: (T) ⇒ Option[S])(implicit serializedFormat: Format[S]): Format[T]

Conveniently construct a format for a case class type.

For example:
```
case class StorageValue(value: JsObject, version: String)

object StorageValue {
  implicit val jsonFormat: Format[StorageValue] =
    JsonFormats.caseClassFormat((apply _).tupled, unapply)
}
```
def caseClassOFormat[T, S](apply: (S) ⇒ T, unapply: (T) ⇒ Option[S])(implicit serializedFormat: OFormat[S]): OFormat[T]

Like caseClassFormat but for OFormat.

def formatWithDefaults[T](delegate: OFormat[T], readsDefaults: JsObject): OFormat[T]

Returns a new format that delegates to delegate for JSON parsing, but adds default values before calling reads.
Returns a new format that delegates to delegate for JSON parsing, but adds default values before calling reads. Unfortunately delegate must be passed in and not constructed automatically due to Play JSON library macro limitations.
