Class XStreamSagaSerializer

java.lang.Object
  org.axonframework.saga.repository.XStreamSagaSerializer

All Implemented Interfaces:

SagaSerializer

public class XStreamSagaSerializer
extends Object
implements SagaSerializer

Implementation of the SagaSerializer that uses XStream to serialize Saga instances to XML. The serialized form returned by this serializer is more flexible, making it safe to use if the Saga's class definition needs to change, and existing Sagas need to be converted.
