public class BallControl
extends java.applet.Applet

The "Controller" in a Model-View-Controller architecture Sets up the appropriate wiring between the model and the view. Uses adapters to respond to user input and notifies the model and the view to update accordingly.
Note: This controller is designed to also be used as an applet in a web page, hence, it extends java.applet.Applet. It also contains extra code to properly set the defaultWindowClosingOperation of the view to WindowConstants.EXIT_ON_CLOSE when run as an applicatio, i.e. from main() which calls the parameterized constructor, and to WindowConstants.HIDE_ON_CLOSE when run as an applet, i.e. the no-parameter constructor is called.

Constant Field Values

_view

private BallGUI _view

The view being used

_model

private BallModel _model

The model being used

Constructor Detail

BallControl

public BallControl()

This constructor is called when the controller is being run as an applet. The defaultWindowCloseOperation of the view is set to WindowConstants.HIDE_ON_CLOSE by delegating to the other constructor with this value.

BallControl

public BallControl(int defaultCloseOperation)

Constructor for the BallControl class Instantiates the BallGUI frame with the required ILambdas for making a ball, clearing the balls from the screen and for painting the balls onto the Container Starts the timer up.
This constructor sets the view's defaultCloseOperation to the given value

Parameters:

defaultCloseOperation - The view's defaultCloseOperation value.

Method Detail

start

public void start()

Start the entire system by starting the model and the view.

Overrides:

start in class java.applet.Applet

main

public static void main(java.lang.String[] args)

Entry point to the program. Instantiates a BallControl object, starts it and goes away. The controller is instantiated with a defaultCloseOperation value of WindowsConstants.EXIT_ON_CLOSE
