Class Pair

java.lang.Object
  org.openuat.util.Pair

All Implemented Interfaces:

java.lang.Runnable, ifListener, ifPair

public class Pair
extends java.lang.Object
implements ifPair

Author:

Lukas Wallentin Must be run as a thread!!! Example: comm = new Comm(); Thread commThread = new Thread(comm); commThread.start(); This Class provides basic key management functions. In the background it uses the Stored keys to generate additional keys between its two hop neighbors.
