Class DecoratorFigure

java.lang.Object

CH.ifa.draw.standard.AbstractFigure

CH.ifa.draw.standard.DecoratorFigure

All Implemented Interfaces:

Figure, FigureChangeListener, Storable, java.io.Serializable, java.lang.Cloneable, java.util.EventListener

Direct Known Subclasses:

AnimationDecorator, BorderDecorator

public abstract class DecoratorFigure
extends AbstractFigure
implements FigureChangeListener

DecoratorFigure can be used to decorate other figures with decorations like borders. Decorator forwards all the methods to their contained figure. Subclasses can selectively override these methods to extend and filter their behavior. Design Patterns

Decorator
DecoratorFigure is a decorator.
