public class ScriptableOutputStream
Class ScriptableOutputStream is an ObjectOutputStream used to serialize JavaScript objects and functions. Note that compiled functions currently cannot be serialized, only interpreted functions. The top-level scope containing the object is not written out, but is instead replaced with another top-level object when the ScriptableInputStream reads in this object. Also, object corresponding to names added to the exclude list are not written out but instead are looked up during deserialization. This approach avoids the creation of duplicate copies of standard objects during deserialization.
