java.lang.Object
  org.nuiton.topia.replication.TopiaReplicationContext

public class TopiaReplicationContext
extends Object

Defines the context used to replicate.

It contains :

• the replicationModel
• data sources involved ([@link #sourceTx}, targetTx)
• universe of data to replicate data
• nodes that has been treated successfully treated
