an interface implemented by applications which wish to be involved in recovering saved participants after a crash.
public interface XTSATRecoveryModule
{
    
called during recovery processing to allow an application to identify a participant id belonging to one of its participants and recreate the participant by deserializing it from the supplied object input stream. n.b. this is only appropriate in case the participant was originally saved using serialization.

Parameters:
id the id used when the participant was created
stream a stream from which the application should deserialise the participant if it recognises that the id belongs to the module's application
Returns:
Throws:
java.lang.Exception if an error occurs deserializing the durable participant
    public Durable2PCParticipant deserialize(String idObjectInputStream streamthrows Exception;

    
called during recovery processing to allow an application to identify a participant id belonging to one of its participants and use the saved recovery state to recreate the participant. n.b. this is only appropriate in case the participant was originally saved after being converted to a byte array using the PersistibleATParticipant interface.

Parameters:
id the id used when the participant was created
recoveryState a byte array returned form the original participant via a call to method getRecoveryState of interface PersistableATParticipant
Returns:
Throws:
java.lang.Exception if an error occurs converting the recoveryState back to a durable participant
    public Durable2PCParticipant recreate(String idbyte[] recoveryStatethrows Exception;

    
participant recovery modules may need to perform special processing when the a recovery scan has completed. in particular it is only after the first recovery scan has completed they can identify whether locally prepared changes are accompanied by a recreated participant and roll back changes for those with no such participant.
