Method Detail

route

public void route(PastryNettable n,
                  PastryLocation pl)

isClosest

public boolean isClosest(PastryLocation key)

Called by the layered Pastry application to check if the local pastry node is the one that is currently closest to the object key id.

Parameters:

key - -- the object key id

Returns:

true if the local node is currently the closest to the key.

update

public void update(PastryNode p)

networkRoute

public boolean networkRoute(PastryLocation pl,
                            PastryNettable n)

sendNettable

                            PastryNettable n)

addLocation

public void addLocation(PastryLocation pLoc)

Adds a PastryLocation to the node. First tries LeafSet, then tries routing table.

Parameters:

pLoc - -- node location to add

getLocation

public PastryLocation getLocation()

getRoutingTable

public RoutingTable getRoutingTable()

getLeafSet

public LeafSet getLeafSet()

mergeLeafset

public boolean mergeLeafset(LeafSet leafset,
                            PastryLocation from)

broadcast

private void broadcast(java.util.Collection pLocTargets,
                       PastryNettable n)

broadcast
