Constructor Detail

SocketPastryNode

public SocketPastryNode(NodeId id,
                        Environment e)

Constructor

Parameters:

id - The NodeId of this Pastry node.

e - DESCRIBE THE PARAMETER

Method Detail

getSocketSourceRouteManager

public SocketSourceRouteManager getSocketSourceRouteManager()

Returns the SocketSourceRouteManager for this pastry node.

Returns:

The SocketSourceRouteManager for this pastry node.

getNodeHandlePool

public DistNodeHandlePool getNodeHandlePool()

Returns the WireNodeHandlePool for this pastry node.

Specified by:

getNodeHandlePool in class DistPastryNode

Returns:

The WireNodeHandlePool for this pastry node.

setSocketElements

public void setSocketElements(EpochInetSocketAddress address,
                              SocketSourceRouteManager srManager,
                              SocketNodeHandlePool pool,
                              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.

lsmf - Leaf set maintenance frequency. 0 means never.

rsmf - Route set maintenance frequency. 0 means never.

pool - The new SocketElements value

srManager - 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() !!!

Overrides:

destroy in class DistPastryNode
