java.lang.Object

java.io.InputStream

java.io.ObjectInputStream

com.persistit.Value.OldValueInputStream

All Implemented Interfaces:

Closeable, DataInput, ObjectInput, ObjectStreamConstants, AutoCloseable

Enclosing class:

Value

public static class Value.OldValueInputStream
extends ObjectInputStream

An ObjectOutputStream that reads bytes from this Value using standard Java serialization. If constructed with a non-null ObjectStreamClass, then readStreamHeader and readClassDescriptor are overridden to read nothing because the SerialValueCoder will already have access to the necessary information.
