Field Detail

public MyApp(Node node)

Method Detail

getNode

public Node getNode()

routeMyMsg

public void routeMyMsg(Id id)

Called to route a message to the id

routeMyMsgDirect

public void routeMyMsgDirect(NodeHandle nh)

Called to directly send a message to the nh

deliver

public void deliver(Id id,
                    Message message)

Called when we receive a message.

Specified by:

id - The destination id of the message

message - The message being sent

update

public void update(NodeHandle handle,
                   boolean joined)

Called when you hear about a new neighbor. Don't worry about this method for now.

Specified by:

update in interface Application

Parameters:

handle - The handle that has joined/left

joined - Whether the node has joined or left

forward

public boolean forward(RouteMessage message)

Description copied from interface: Application

This method is invoked on applications when the underlying node is about to forward the given message with the provided target to the specified next hop. Applications can change the contents of the message, specify a different nextHop (through re-routing), or completely terminate the message.

Specified by:

forward in interface Application

Parameters:

message - The message being sent, containing an internal message along with a destination key and nodeHandle next hop.

Returns:

true if it should continue along the path. false will deliver it locally
