This class represents a named field of a specified type (i.e., a specified Class). When a class serializes itself by writing a set of fields that are different from the fields it uses in its own implementation, it defines the set of fields to be written with an array of ObjectStreamField objects. This array should be the value of a private static field named serialPersistentFields. The methods of this class are used internally by the serialization mechanism and are not typically used elsewhere. See also ObjectOutputStream.PutField and ObjectInputStream.GetField.
