public abstract class FigureDecorator extends AbstractFigureContainer
This class is a reasonable example of the Decorator design pattern, hence its name.
| Constructor and Description |
|---|
FigureDecorator() |
| Modifier and Type | Method and Description |
|---|---|
void |
add(Figure f)
Add a figure.
|
boolean |
contains(Figure f)
Test if the given figure is the one contained by this decorator.
|
Iterator |
figures()
Return an iteration containing the one child.
|
Iterator |
figuresFromBack()
Return an iteration containing the one child.
|
Iterator |
figuresFromFront()
Return an iteration containing the one child.
|
Rectangle2D |
getBounds()
Get the bounds of this figure, which is by default the
same as the child figure, if there is one, or a very small
rectangle if there isn't.
|
Figure |
getChild()
Get the child figure, or null if there isn't one.
|
FigureContainer |
getContainer()
Get the container, which is defined as the lowest
ancestor that is not a FigureDecorator.
|
Figure |
getDecoratedFigure()
Get the decorated figure, which is defined as the highest
descendent that is not a decorator.
|
int |
getFigureCount()
Return zero if there is no child, or one if there is.
|
Shape |
getShape()
Get the outline shape of this figure, which is by default the
same as the child figure, if there is one, or a very small
rectangle if there isn't.
|
boolean |
hit(Rectangle2D r)
Test if the child is hit.
|
abstract FigureDecorator |
newInstance(Figure f)
Create a new instance of this figure decorator, modelled
on this one.
|
void |
paint(Graphics2D g)
Paint the figure.
|
void |
remove(Figure f)
Remove a figure.
|
protected void |
replaceChild(Figure child,
Figure replacement)
Replace the first figure, which must be a child, with the
second, which must not be a child.
|
void |
setChild(Figure f)
Set the child figure.
|
void |
transform(AffineTransform at)
Transform the figure with the supplied transform.
