AbstractShape

java.lang.Object
- com.bric.geom.AbstractShape

All Implemented Interfaces:

Shape

Direct Known Subclasses:

CubicPath, CurvedPolyline, MutablePath, Spiral2D
```
public abstract class AbstractShape
extends Object
implements Shape
```
This is a class that implements all Shape methods except for getPathIterator(AffineTransform). Because all the other methods consult getPathIterator() it is essential that when subclasses implement that method it be very light. See MutablePath as a possible example.

contains
```
public boolean contains(Point2D p)
```

contains

public boolean contains(Rectangle2D r)

contains

public boolean contains(Point2D p,
                        AffineTransform transform)

contains

public boolean contains(Rectangle2D r,
                        AffineTransform transform)

getWindingRule
```
public abstract int getWindingRule()
```

contains

public boolean contains(double x,
                        double y)

contains

public boolean contains(double x,
                        double y,
                        AffineTransform transform)

countCrossings
```
protected int countCrossings(double x,
                             double y,
                             AffineTransform transform)
```
This counts the number of crossings from (-infinity,y) to (x,y). This total is used in combination with the winding rule to determine when a point is inside a shape.

identifyCrossings

protected boolean identifyCrossings(double x,
                                    double y,
                                    double w,
                                    double h,
                                    AffineTransform transform)

This checks to see if the rectangle argument ever crosses this shape. This method returns immediately when/if it finds proof of an intersection.

intersects

public boolean intersects(double x,
                          double y,
                          double w,
                          double h)

intersects

public boolean intersects(double x,
                          double y,
                          double w,
                          double h,
                          AffineTransform transform)

contains

public boolean contains(double x,
                        double y,
                        double w,
                        double h)

contains

public boolean contains(double x,
                        double y,
                        double w,
                        double h,
                        AffineTransform transform)
