DirectPastryNodeFactory

public DirectPastryNodeFactory(rice.pastry.NodeIdFactory nf,
                               rice.pastry.direct.NetworkSimulator sim)

Method Detail

getNetworkSimulator

public rice.pastry.direct.NetworkSimulator getNetworkSimulator()

Manufacture a new Pastry node.

Specified by:

newNode in class PastryNodeFactory

Parameters:

bootstrap - The node handle to bootstrap off of

Returns:

a new PastryNode

newNode

public rice.pastry.PastryNode newNode(rice.pastry.NodeHandle bootstrap,
                                      rice.pastry.NodeId nodeId)

Manufacture a new Pastry node.

Specified by:

newNode in class PastryNodeFactory

Parameters:

bootstrap - The node handle to bootstrap off of

nodeId - The nodeId of the new node

Returns:

a new PastryNode

getLeafSet

public rice.pastry.leafset.LeafSet getLeafSet(rice.pastry.NodeHandle handle)

This method returns the remote leafset of the provided handle to the caller, in a protocol-dependent fashion. Note that this method may block while sending the message across the wire.

Specified by:

getLeafSet in class PastryNodeFactory

Parameters:

handle - The node to connect to

Returns:

The leafset of the remote node

getRouteRow

public rice.pastry.routing.RouteSet[] getRouteRow(rice.pastry.NodeHandle handle,
                                                  int row)

This method returns the remote route row of the provided handle to the caller, in a protocol-dependent fashion. Note that this method may block while sending the message across the wire.

Specified by:

getRouteRow in class PastryNodeFactory

Parameters:

handle - The node to connect to

row - The row number to retrieve

Returns:

The route row of the remote node

getProximity

public int getProximity(rice.pastry.NodeHandle local,
                        rice.pastry.NodeHandle remote)

This method determines and returns the proximity of the current local node the provided NodeHandle. This will need to be done in a protocol- dependent fashion and may need to be done in a special way.

Specified by:

getProximity in class PastryNodeFactory

Parameters:

remote - The handle to determine the proximity of

Returns:

The proximity of the provided handle
