Class ExternalizedObject

java.lang.Object
  org.jboss.marshalling.serial.ExternalizedObject

All Implemented Interfaces:

java.io.Externalizable, java.io.Serializable, Creator

public final class ExternalizedObject
extends java.lang.Object
implements java.io.Externalizable, Creator

An externalized object. This wrapper allows an object that was written with an Externalizer to be read by standard Java serialization. Note that if an externalized object's child object graph ever refers to the original object, there will be an error in the reconstructed object graph such that those references will refer to this wrapper object rather than the properly externalized object.
