Class EmulatedNode

java.lang.Object
  EmulatedNode

public class EmulatedNode

extends java.lang.Object

   
 Keeps track of information about an emulated node
 Emulated node uses a TCP socket to talk to the Trawler, but send and receive messages directly
 to other emulated nodes using UDP.

                    java.net.InetAddress ipAddress,
                    int port)

Create a new EmulatedNode

Parameters:

socket - The socket to use to talk to the emulated node

out - An outputstream to use to send data across the socket
