Class TestConnection

java.lang.Object
  java.lang.Thread
      ctf.network.tcp.Connection
          ctf.network.tcp.TestConnection

All Implemented Interfaces:

java.lang.Runnable

public class TestConnection
extends Connection

A connection that times out after 100 ms (the maximum allowable latency according to the CTF specification). In reality, we allow more delay, since we can't control things like processor and thread scheduling.
