Methods

o imageUpdate 
  public synchronized boolean imageUpdate(Image img,
                                          int infoflags,
                                          int x,
                                          int y,
                                          int width,
                                          int height)
Override of Component.imageUpdate, an implementation of ImageObserver.imageUpdate. Called by an image producer every time an interesting point in image loading occurs.
Parameters:
img - The image that we're talking about.
infoflags - The state of the image-load - a constant from ImageObservers public variable set.
Overrides:
imageUpdate in class Component
o start 
  public void start()
start - Whenever a user visits our page, Applet calls this. This is an override of an Applet method. Creates a thread and passes this AgentLauncher into it. Works because we implement the Runnable method.
Overrides:
start in class Applet
o showProperties 
  public void showProperties()
o Dispatch 
  public void Dispatch()
Dispatch the current Agent. currentAgent is an instance of the Agent we wish to dispatch, and he has already configured himself via Agent.configure. We need to get his arguments as a Vector of Strings, create a dispatcher, then tell the dispatcher to dispatch using the currentAgent with those arguments.

o LoadAgentClass 
  public static void LoadAgentClass(Frame f,
                                    String selected)
o StopAgent 
  public void StopAgent(String cid)
o LoadTest 
  public void LoadTest()
o getFrame 
  public Frame getFrame()
Get the Frame window that is the parent of all the windows currently on the screen. Every application has ONE Frame that can be found by trolling through the tree of Containers that makes up the hierarchy of windows in a Java application.
Returns:
The Frame that is the ultimate parent of the current Component.
o addAnimation 
  public void addAnimation()
o addAgentFace 
  public void addAgentFace(String server)
o reportResult 
  public void reportResult(String server,
                           String url)
A method called by the message processing code (AgentDispatcher) to change an agents state from running to finished with or without results.
Parameters:
url - The URL of the results file. If null, there were no results.
server - The name of the server. We find the AgentFace we need to change by searching on this name.
o setRunning 
  public void setRunning(int index)
o stop 
  public void stop()
Stop this thread.
Overrides:
stop in class Applet
o run 
  public void run()
The main loop for the main thread.
o clicked 
  public boolean clicked(int x,

o init 
  public void init()
Initialize the applet. Resize and load images.
Overrides:

o startDispatch 
  public void startDispatch()
startDispatch - Called when the user has chosen to dispatch an Agent. Sends the Agent to our ServerList and opens the ResultFile.
o endDispatch 
  public void endDispatch()
endDispatch - Called when the user has decided to call off this search. Closes the results file and notifies the connectionHandler to kill off any Agents that report in after this point.
o addAgentDisplay 
  public void addAgentDisplay(String server)
The original addAgentDisplay method. Runs through array looking for a spot to place the new AgentFace.
Parameters:
server - The name of the server that's running this Agent.
o addAgentDisplay1 
  public void addAgentDisplay1(String server)
The new addAgentDisplay method. Runs through array looking for a spot to place the new AgentFace, letting us throw exception if we overrun array.
Parameters:
server - The name of the server that's running this Agent.
o MessageBox

o showResults 
  public void showResults(String s,
                          String urls)
showResults -
o showNoResults 
  public void showNoResults(String s)
showNoResults -
o reportResults 
  public void reportResults(Result r)
reportResults - When an Agent sends the result of a search to the AgentConnectionHandler, the handler calls this to place the results pointer into the results HTML doc and to visually notify the user that this server has finished with whatever results.
o LoadAnimationImages 
  public synchronized void LoadAnimationImages()
Load all the images this applet needs for its animation sequences. Blocks until all the images have been loaded over the net OR one of the images reports a load error.
