public class SerialInput
extends ClassResolver.Stream

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.

public SerialInput(java.io.InputStream in,
                   ClassCatalog classCatalog)
            throws java.io.IOException

Creates a serial input stream.

Parameters:

in - is the input stream from which compact serialized objects will be read.

classCatalog - is the catalog containing the class descriptions for the serialized objects.

Throws:

java.io.IOException - if an I/O error occurs while reading stream header.
