Examples of java.io.SerialCallbackContext

java.io.SerialCallbackContext
Context during upcalls from object stream to class-defined readObject/writeObject methods. Holds object currently being deserialized and descriptor for current class. This context keeps track of the thread it was constructed on, and allows only a single call of defaultReadObject, readFields, defaultWriteObject or writeFields which must be invoked on the same thread before the class's readObject/writeObject method has returned. If not set to the current thread, the getObj method throws NotActiveException.
