alice.tuplemedium.runtime
Class User  view User download User.java

java.lang.Object
  extended byalice.tuplemedium.runtime.User
All Implemented Interfaces:
alice.tuplemedium.VMListener
public class User
extends java.lang.Object
implements alice.tuplemedium.VMListener

this is the basic class for developing tuple media TCP/IP user.

if the user is recognized to be local the interactions with the tuple centre virtual machines are realized directly, bypassing TCP/IP protocol (this is possible because of there is only one daemon service installed on a java VM).

if the tuple centre is remote, this class provide the user proxy (or connector) to remote service In this case the class UserListener is the related stub or acceptor, on the remote (daemon) side.
