1.35 - * Only the identity of the class of an Externalizable instance is
1.36 - * written in the serialization stream and it is the responsibility
1.37 - * of the class to save and restore the contents of its instances.
1.38 - *
1.39 - * The writeExternal and readExternal methods of the Externalizable
1.40 - * interface are implemented by a class to give the class complete
1.41 - * control over the format and contents of the stream for an object
1.42 - * and its supertypes. These methods must explicitly
1.43 - * coordinate with the supertype to save its state. These methods supersede
1.44 - * customized implementations of writeObject and readObject methods.<br>
1.45 - *
1.46 - * Object Serialization uses the Serializable and Externalizable
1.47 - * interfaces. Object persistence mechanisms can use them as well. Each
1.48 - * object to be stored is tested for the Externalizable interface. If
1.49 - * the object supports Externalizable, the writeExternal method is called. If the
1.50 - * object does not support Externalizable and does implement
1.51 - * Serializable, the object is saved using
1.52 - * ObjectOutputStream. <br> When an Externalizable object is
1.53 - * reconstructed, an instance is created using the public no-arg
1.54 - * constructor, then the readExternal method called. Serializable
1.55 - * objects are restored by reading them from an ObjectInputStream.<br>
1.56 - *
1.57 - * An Externalizable instance can designate a substitution object via
1.58 - * the writeReplace and readResolve methods documented in the Serializable
1.59 - * interface.<br>
