Class ADecoratorPaintStrategy

java.lang.Object
  ballwar.model.paint.ADecoratorPaintStrategy

All Implemented Interfaces:

IPaintStrategy

Direct Known Subclasses:

FixedColorDecoratorPaintStrategy

public abstract class ADecoratorPaintStrategy
extends Object
implements IPaintStrategy

Abstract class that provides default behavior for subclasses that will decorate another IPaintStrategy to add functionality to that strategy. All this class's methods do is to simply delegate to the decoree. A subclass should override one or more methods, adding additional processing either before or after delegating to the decoree. Note that this class cannot be used by the BallWar system directly as it lacks a no-parameter constructor.

Field Summary

decoree The "decoree" paint strategy whose methods are being augmented by this decorator paint strategy.

Method Summary

void	init(Ball host) Default behavior is to simply delegate to the decoree's init method
void	paint(Graphics g, Ball host) Default behavior is to simply delegate to the decoree's paint method
void	paintXfrm(Graphics g, Ball host, AffineTransform at) Default behavior is to simply delegate to the decoree's paintXfrm method
