serialize

public void serialize(ObjectOutputStream oos)
               throws IOException

Custom serialization routine used during serialization of a Session/PersistenceContext for increased performance.

参数:

oos - The stream to which we should write the serial data.

抛出:

IOException

deserialize

public static EntityUniqueKey deserialize(ObjectInputStream ois,
                                          SessionImplementor session)
                                   throws IOException,
                                          ClassNotFoundException

Custom deserialization routine used during deserialization of a Session/PersistenceContext for increased performance.

参数:

ois - The stream from which to read the entry.

session - The session being deserialized.

返回:

The deserialized EntityEntry

抛出:

IOException

ClassNotFoundException
