  public NuclearPlant()

  public void init()

Initialize the applet. Sets the applet size, creates the plant components, and creates the simulator.

Overrides:

init in class Applet

paint

  public void paint(Graphics g)

Update the plant display

Parameters:

g - Graphics context to paint in

Overrides:

paint in class Applet

update

  public void update(Graphics g)

Update without erasing background

Parameters:

g - Graphics context to update in

Overrides:

update in class Applet

mouseDown

  public void mouseDown(int x,
                        int y)

Handle mouseDown events. This method distributes the message by calling the mouseDown methods for the appropriate plant components

Parameters:

x - The X coordinate

y - The Y coordinate

Overrides:

mouseDown in class Applet

mouseDrag

  public void mouseDrag(int x,
                        int y)

Handle mouseDrag events. This method distributes the message by calling the mouseDrag methods for the appropriate plant components

Parameters:

x - The X coordinate

y - The Y coordinate

Overrides:

mouseDrag in class Applet

mouseUp

  public void mouseUp(int x,
                      int y)

Handle mouseUp events. This method distributes the message by calling the mouseUp methods for the appropriate plant components

Parameters:

x - The X coordinate

y - The Y coordinate

Overrides:

mouseUp in class Applet

rotatePumps

  protected void rotatePumps()

Rotate the pumps one step. (Only pumps with rpm > 0 are rotated.)

waterWave

  protected void waterWave()

Move the waves on the water surfaces in the tanks

startReactor

  public void startReactor()

Start the simulation

timeStep

  public void timeStep(int n)

Run the simulation n steps. Uses the crurrent simulator to calculate the next states

Parameters:

n - The number of steps

blow

  public void blow(Component device)

Blow up a device.

Parameters:

device - The device to blow (e.g., a turbine object)

stopReactor

  public void stopReactor()

Stop the simulation

crashSound

  public void crashSound(int n)

Play a crash sound. This method is called when plant components blow up.

Parameters:

n - Duration

run

  public void run()

Run the animation thread. This method is called when the animation thread is started.

start

  public void start()

Start the applet. Creates the animation thread and opens the window for the sequence control buttons

Overrides:

start in class Applet

stop

  public void stop()

Stop the applet. Stops the animation thread and closes the window for the sequence control buttons

Overrides:

stop in class Applet

destroy

  public void destroy()

Destroy the applet. This method is called by the browser when the applet is destroyed. It disposes the window for the sequence control buttons.

Overrides:

destroy in class Applet
