 * Externalization allows a class to specify the methods to be used to
 * write the object's contents to a stream and to read them back.  The
 * Externalizable interface's writeExternal and readExternal methods
 * are implemented by a class to
 * give the class complete control over the format and contents of the
 * stream for an object and its supertypes. These methods must explicitly
 * coordinate with the supertype to save its state. <br>
 * Object Serialization uses the Serializable and Externalizable
 * interfaces.  Object persistence mechanisms may use them also.  Each
 * object to be stored is tested for the Externalizable interface. If
 * the object supports it, the writeExternal method is called. If the
 * object does not support Externalizable and does implement
 * Serializable the object should be saved using
 * ObjectOutputStream. <br> When an Externalizable object is to be
 * reconstructed, an instance is created using the public no-arg
 * constructor and the readExternal method called.  Serializable
 * objects are restored by reading them from an ObjectInputStream.

     * The object implements the writeExternal method to save its contents
     * by calling the methods of DataOutput for its primitive values or
     * calling the writeObject method of ObjectOutput for objects, strings
     * and arrays.
     * @exception IOException Includes any I/O exceptions that may occur

    void writeExternal(ObjectOutput out) throws IOException;

     * The object implements the readExternal method to restore its
     * contents by calling the methods of DataInput for primitive
     * types and readObject for objects, strings and arrays.  The
     * readExternal method must read the values in the same sequence
     * and with the same types as were written by writeExternal.
     * @exception ClassNotFoundException If the class for an object being
     *              restored cannot be found.
     * @since     JDK1.1
    void readExternal(ObjectInput in) throws IOException, ClassNotFoundException;
