Constructor Detail

ScribeTutorial

public ScribeTutorial(int bindport,
                      java.net.InetSocketAddress bootaddress,
                      int numNodes,
                      Environment env)
               throws java.lang.Exception

Based on the rice.tutorial.lesson4.DistTutorial This constructor launches numNodes PastryNodes. They will bootstrap to an existing ring if one exists at the specified location, otherwise it will start a new ring.

Parameters:

bindport - the local port to bind to

bootaddress - the IP:port of the node to boot from

numNodes - the number of nodes to create in this JVM

env - the Environment

Throws:

java.lang.Exception - DESCRIBE THE EXCEPTION

Method Detail

getRoot

public static NodeHandle getRoot(NodeHandle seed,
                                 java.util.Hashtable appTable)

Recursively crawl up the tree to find the root.

Parameters:

seed - DESCRIBE THE PARAMETER

appTable - DESCRIBE THE PARAMETER

Returns:

The Root value

printTree

public static void printTree(java.util.Vector apps)

Note that this function only works because we have global knowledge. Doing this in an actual distributed environment will take some more work.

Parameters:

apps - Vector of the applicatoins.

recursivelyPrintChildren

public static void recursivelyPrintChildren(NodeHandle curNode,
                                            int recursionDepth,
                                            java.util.Hashtable appTable)

Print's self, then children.

Parameters:

curNode - DESCRIBE THE PARAMETER

recursionDepth - DESCRIBE THE PARAMETER

appTable - DESCRIBE THE PARAMETER

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

Usage: java [-cp FreePastry- .jar] rice.tutorial.lesson6.ScribeTutorial localbindport bootIP bootPort numNodes example java rice.tutorial.DistTutorial 9001 pokey.cs.almamater.edu 9001

Parameters:

args - The command line arguments

Throws:
