public class SerialInput
extends ObjectInputStream

A specialized ObjectInputStream that gets class description information from a ClassCatalog. It is used by SerialBinding.

This class is used instead of an ObjectInputStream, which it extends, to read an object stream written by the SerialOutput class. For reading objects from a database normally one of the serial binding classes is used. SerialInput is used when an ObjectInputStream is needed along with compact storage. A ClassCatalog must be supplied, however, to stored shared class descriptions.
