Method Detail

constructNodeAdditionRequest

public byte[] constructNodeAdditionRequest(int[] levels,
                                           boolean from)

This method is responsible for constructing the node addition request. A node specifies the kind of gateways it seeks to be in the integer array, while specifying the to/from charachteristics of the node addition request

Parameters:

levels - - Integer array specifying the kind of gateways the node seeks to be.

from - - Speicification of the to/from relationship for node addition.

constructNodeAdditionResponse

public byte[] constructNodeAdditionResponse(ProtocolID requestId,
                                            int requestedLevel,
                                            int systemLevel,
                                            NodeAddress addressAssigned,
                                            NodeAddress assignedBy,
                                            NodeAddress connectedTo)

constructNodeAdddressRequest

public byte[] constructNodeAdddressRequest(int requestedLevel,
                                           int systemLevel,
                                           ProtocolID requestId,
                                           Destinations origin,
                                           Destinations toReach,
                                           Destinations traversedSoFar)

constructNodeAddressResponse

public byte[] constructNodeAddressResponse(int requestedLevel,
                                           int systemLevel,
                                           ProtocolID requestId,
                                           NodeAddress addressAssigned,
                                           NodeAddress assignedBy,
                                           Destinations toReach,
                                           Destinations traversedSoFar)

routeNodeAddressResponse

public void routeNodeAddressResponse(NodeAddress assignedAddress,
                                     int level,
                                     NodeAddress toAddress)

When an address has been created it needs to be routed back to the node where this node was created.
