Constant Field Values

_view

private BallGUI _view

The system's view (GUI).

_windowListener

private WindowListener _windowListener

The window listener used by the view when the window is closed. By default, it does nothing, as needed for an applet. One of the constructors can be used to set this value to something else, as needed when run as an application.

_model

private BallModel _model

The system's model.

_keysPnl

private OptionPanel _keysPnl

An OptionPanel used to display the movement keys. This panel is added to the view.

Constructor Detail

BallControl

public BallControl()

Constructor for the BallControl class Used when run as an applet.

BallControl

public BallControl(WindowListener wl)

Constructor for the BallControl class Used when run as an application. Called by main()

Parameters:

wl - WindowListener that should call System.exit(0)

Method Detail

init

public void init()

Initializes the system by instantiating the view and the model and all the necessary adapters.

Overrides:

init in class Applet

start

public void start()

Starts the systems running by validating the view and setting to be visible and starting the model.

Overrides:

start in class Applet

fixName

private String fixName(String packageName,
                       Object classname,
                       String restOfName)

Convenience method to add the rest of a strategy's classname plus the word "Strategy" at the end of the classname. Assumes that the class is located in the ballwar.model.strategy package.

Parameters:

classname - The classname, assuming that it is in the ballwar.model.strategy package and ends with the word "Strategy".

Returns:

The complete, augmented classname.

main

public static void main(String[] args)

Entry point to the program. Instantiates a BallControl object with a WindowListener (WindowAdapater) that calls System.exit(0) when the window is closed.
