Class SerialInput

java.lang.Object
  java.io.InputStream
      java.io.ObjectInputStream
          com.sleepycat.bind.serial.SerialInput

All Implemented Interfaces:

DataInput, ObjectInput, ObjectStreamConstants

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.
