Constructor Detail

DirectPastryNodeFactory

public DirectPastryNodeFactory(NodeIdFactory nf,
                               NetworkSimulator sim)

Constructor for DirectPastryNodeFactory.

Parameters:

nf - DESCRIBE THE PARAMETER

sim - DESCRIBE THE PARAMETER

Method Detail

getNetworkSimulator

public NetworkSimulator getNetworkSimulator()

Gets the NetworkSimulator attribute of the DirectPastryNodeFactory object

Returns:

The NetworkSimulator value

getLeafSet

public LeafSet getLeafSet(NodeHandle handle)
                   throws java.io.IOException

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

Throws:

java.io.IOException - DESCRIBE THE EXCEPTION

getRouteRow

public RouteSet[] getRouteRow(NodeHandle handle,

                       throws java.io.IOException

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

Throws:

java.io.IOException - DESCRIBE THE EXCEPTION

getProximity

public int getProximity(NodeHandle local,
                        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:

a new PastryNode

newNode

public PastryNode newNode(NodeHandle bootstrap,
                          NodeId nodeId)

Manufacture a new Pastry node.

Specified by:

newNode in class PastryNodeFactory

Parameters:

bootstrap - DESCRIBE THE PARAMETER

nodeId - DESCRIBE THE PARAMETER

Returns:

a new PastryNode
