Class JStatefulInputStream

java.lang.Object
  java.io.InputStream
      java.io.ObjectInputStream
          org.ow2.jonas.lib.ejb21.JStatefulInputStream

All Implemented Interfaces:

Closeable, DataInput, ObjectInput, ObjectStreamConstants

Direct Known Subclasses:

JRepStatefulInputStream

public class JStatefulInputStream
extends ObjectInputStream

Extends ObjectInputStream because we want to enable resolveObject. This class is very related to JStatefulOutputStream

Method Detail

resolveObject

protected Object resolveObject(Object obj)
                        throws IOException

We must care about some object types. See EJB spec. 7.4.1

Overrides:

resolveObject in class ObjectInputStream

Parameters:

obj - serialized field

Returns:

resolved object

Throws:

IOException

resolveClass

protected Class resolveClass(ObjectStreamClass v)
                      throws IOException,
                             ClassNotFoundException

Use the thread context class loader to resolve the class

Overrides:

resolveClass in class ObjectInputStream

Parameters:

v - class to resolve

Returns:

class resolved

Throws:

IOException - thrown by the underlying InputStream.

ClassNotFoundException - thrown by the underlying InputStream.
