MultiringNodeCollection(MultiringNode node, int BASE)
Constructor

Method Summary

void	addNode(MultiringNode node) This method allows other nodes to be dynamically added to the node collection.
protected void	broadcastNewNode(MultiringNode node) This method informs all of the existing nodes of the newly added node, and informs the newly added node of all of the existing nodes.
protected int	getLength(RingId a) This method returns the length of the given ringId
protected int	getLengthOfSharedPrefix(RingId a, RingId b) This method returns the length of the shared prefix, in bytes, of the two provided ringIds by comparing the ring values.
protected void	route(RingId id, Message message, java.lang.String application) This method returns the best next-hop to a given target, using ring hopping, if one exists.

Field Detail

BASE

public int BASE

The routing base for ring ids, in bytes

nodes

protected java.util.Vector nodes

The list of nodes in the collection

Constructor Detail

MultiringNodeCollection

public MultiringNodeCollection(MultiringNode node,
                               int BASE)

Constructor

Parameters:

node - The node to base this node off of

Method Detail

addNode

public void addNode(MultiringNode node)

This method allows other nodes to be dynamically added to the node collection. Using this method, a node is added to the collection, and it is told of all of the other nodes in the collection. Similarly, all of the other nodes in the collection are told of this node.

Parameters:

node - The node to add to the collection

broadcastNewNode

protected void broadcastNewNode(MultiringNode node)

This method informs all of the existing nodes of the newly added node, and informs the newly added node of all of the existing nodes.

Parameters:

node - The node that is being added

route

protected void route(RingId id,
                     Message message,
                     java.lang.String application)

This method returns the best next-hop to a given target, using ring hopping, if one exists. Otherwise, if no local node in the collection is the next hop for the target, null is returned.

Parameters:

id - The target id of the message

message - The message to be sent

hint - A suggested hint

getLength

protected int getLength(RingId a)

This method returns the length of the given ringId

Parameters:

a - The ring Id

Returns:

The number of shared bytes

getLengthOfSharedPrefix

protected int getLengthOfSharedPrefix(RingId a,
                                      RingId b)

This method returns the length of the shared prefix, in bytes, of the two provided ringIds by comparing the ring values.

Parameters:

a - The first Id

b - The second Id

Returns:

The number of shared bytes
