Class magician.Node.ActiveNode 

java.lang.Object
   |
   +----magician.Node.ActiveNode
public class ActiveNode
extends Object
implements ActiveNetsConstants
The main entry point for starting up an Active Node. It contacts the Four11 Information server to obtain configuration information, starts up the PortManager and the Demultiplexer so that they can send and receive Active Network Encapsulation Protocol (ANEP) packets. It also starts up all the processing environments available at the Active Node.
