Class CertifiedNodeIdFactory

java.lang.Object
  rice.pastry.standard.CertifiedNodeIdFactory

All Implemented Interfaces:

NodeIdFactory

public class CertifiedNodeIdFactory

extends java.lang.Object

implements NodeIdFactory

Builds nodeIds in a certified manner, guaranteeing that a given node will always have the same nodeId. NOTE: Actual certification is not yet implemented, rather, using this factory simply guarantees that the node's nodeId will never change.
