protected boolean natted

Constructor Detail

SocketPastryNode

public SocketPastryNode(NodeId id,
                        Environment e)

Constructor

Parameters:

id - The NodeId of this Pastry node.

Method Detail

getSocketSourceRouteManager

public SocketSourceRouteManager getSocketSourceRouteManager()

Returns the SocketSourceRouteManager for this pastry node.

Returns:

The SocketSourceRouteManager for this pastry node.

setSocketElements

public void setSocketElements(EpochInetSocketAddress address,
                              int lsmf,
                              int rsmf)

Helper method which allows the WirePastryNodeFactory to initialize a number of the pastry node's elements.

Parameters:

address - The address of this pastry node.

manager - The socket manager for this pastry node.

lsmf - Leaf set maintenance frequency. 0 means never.

rsmf - Route set maintenance frequency. 0 means never.

sManager - The new SocketElements value

pingManager - The new SocketElements value

pool - The new SocketElements value

doneNode

public void doneNode(NodeHandle bootstrap)

Called after the node is initialized.

Overrides:

doneNode in class DistPastryNode

Parameters:

bootstrap - The node which this node should boot off of.

toString

public java.lang.String toString()

Prints out a String representation of this node

Overrides:

toString in class PastryNode

Returns:

a String

destroy

public void destroy()

Makes this node resign from the network. Is designed to be used for debugging and testing. If run on the SelectorThread, then destroys now. Other threads cause a task to be placed on the selector, and destroyed asap. Make sure to call super.destroy() !!!

Specified by:

destroy in interface Destructable

Overrides:

destroy in class DistPastryNode

coalesce

public NodeHandle coalesce(NodeHandle newHandle)

Specified by:

coalesce in class PastryNode

setSocketSourceRouteManager

public void setSocketSourceRouteManager(SocketSourceRouteManager srManager)

send

public void send(NodeHandle handle,
                 Message message)

Specified by:

send in class PastryNode

isNATted

public boolean isNATted()

testFireWall

public void testFireWall(NodeHandle bootstrap,
                         Continuation c,
                         int timeout)
