public class server_uip_thread
extends java.lang.Thread

class name: server_uip_thread class description: this class is responsible to pass rpc_functions to and receive rpc_functions from a number of client_uips, it use the service of server_uip_receiver_table to implement these functionsm it's also responsible for informing the server_uip_receiver_table to add a new receiver when a client connection is detected

uses the services of class(es): designer(s): Jianxin Zhao (jxzhao@csgrad.cs.vt.edu) implementator(s): finished time: known bugs: JDK version: 1.1.5 side effects:
