Interface CSN

All Superinterfaces:

java.lang.Comparable, java.io.Serializable

All Known Implementing Classes:

SimpleCSN

public interface CSN
extends java.io.Serializable, java.lang.Comparable

Represents 'Change Sequence Number' in LDUP specification. A CSN is a composition of a timestamp, a replica ID and a operation sequence number. It distinguishes a change made on an object on a server, and if two operations take place during the same timeStamp, the operation sequence number makes those operations distinct.

Method Summary

int	getOperationSequence() Returns sequence number of modification.
ReplicaId	getReplicaId() Returns replica ID.
long	getTimestamp() Returns GMT timestamp of modification.
byte[]	toBytes() Returns a byte array representing the CSN
java.lang.String	toOctetString() Returns octet-string representation of this CSN.
