   Example:

   case class Person(name: String, age: Int)
   implicit val formats = org.json4s.DefaultFormats
   Extraction.decompose(Person("joe", 25)) == JObject(JField("age",JInt(25)) :: JField("name",JString("joe")) :: Nil)

20. def loadLazyValValue(a: Any, name: String, defaultValue: Any): Any

    

    Load lazy val value

    Load lazy val value

    This is a fix for failed lazy val serialization from FieldSerializer (see org.json4s.native.LazyValBugs test).

    We do this by finding the hidden lazy method which will have same name as the lazy val name but with suffix "$lzycompute" (for scala v2.10+), then invoke the method if found, and return the value.

    The "$lzycompute" method naming could be changed in future so this method must be adjusted if that happens.

    a

    Object to be serialized

    name

    Field name to be checked

    defaultValue

    Default value if lazy method is not found

    returns

    Value of invoked lazy method if found, else return the default value
