Class MultipleClientNode

java.lang.Object
  cgl.narada.node.MultipleClientNode

All Implemented Interfaces:

NodeDebugFlags

public class MultipleClientNode
extends Object
implements NodeDebugFlags

This class helps us setup multiple client nodes within one process. Each of the these client node's thus setup, can maintain connections to different server nodes within the network. In addition to this, they can also have specific subscription predicates. This class is very useful especially in the testing scenario where we have multiple clients being attached to multiple server nodes within the server network. The sockets are assigned assigned automatically to the client.

Method Summary

void	createMultipleClientNodesToServer(String serverName, int portNum, int numOfNodes, String subscription) This method sets up multiple client nodes with a specific subscription to a given node.
static void	main(String[] args) The test fucntion for the multiple client node
void	setClientPortNum(int portNum) This sets the initial portNum for a muli-client node, individual clients listen to sockets at portNums (which are incremented by 1 for every new client created)

Method Detail

setClientPortNum

public void setClientPortNum(int portNum)

This sets the initial portNum for a muli-client node, individual clients listen to sockets at portNums (which are incremented by 1 for every new client created)

Parameters:

portNum - The starting port number

createMultipleClientNodesToServer

public void createMultipleClientNodesToServer(String serverName,
                                              int portNum,
                                              int numOfNodes,
                                              String subscription)

This method sets up multiple client nodes with a specific subscription to a given node.

Parameters:

serverName - The name of the machine the server node is hosted on.

portNum - The port number that the server node listens to for connections either from clients or servers.

numOfNodes - The number of client nodes that must have a connection to the server.

subscription - The subscription predicate for the client nodes created by this invocation

main

public static void main(String[] args)

The test fucntion for the multiple client node
