Hi,
Serializing joda-time is not supported. Last week a type hint
mechanism was added to support serialization of polymorphic Lists.
This could be generalized a bit so that users can provide de-/
serializers for any type. This could be done for instance using a pair
of partial functions. Something like:
type TypeHint = String
def serialize: PartialFunction[Any, JValue]
def deserialize: PartialFunction[(TypeHint, JValue), Any]
Then a support to serialize joda-time DateTime could be implemented
as:
def serialize(a: Any) = a match {
case d: DateTime => JString("t", toString(d))
}
def deserialize(hint: TypeHint, json: JValue) = (hint, json) match {
case ("DateTime", JString("t", JString(t)) => mkDateTime(t)
}
I'm in a middle of something else right now but will look into this
next.
Cheers Joni
