 public  void add(Point2D pt) 
{
        add(pt.getX(), pt.getY());
}

Adds the Point2D object pt to this Rectangle2D. The resulting Rectangle2D is the smallest Rectangle2D that contains both the original Rectangle2D and the specified Point2D.

After adding a point, a call to contains with the added point as an argument does not necessarily return true. The contains method does not return true for points on the right or bottom edges of a rectangle. Therefore, if the added point falls on the left or bottom edge of the enlarged rectangle, contains returns false for that point.

 public  void add(Rectangle2D r) 
{
        double x1 = Math.min(getMinX(), r.getMinX());
        double x2 = Math.max(getMaxX(), r.getMaxX());
        double y1 = Math.min(getMinY(), r.getMinY());
        double y2 = Math.max(getMaxY(), r.getMaxY());
        setRect(x1, y1, x2 - x1, y2 - y1);
}

Adds a Rectangle2D object to this Rectangle2D. The resulting Rectangle2D is the union of the two Rectangle2D objects.

 public  void add(double newx,
    double newy) 
{
        double x1 = Math.min(getMinX(), newx);
        double x2 = Math.max(getMaxX(), newx);
        double y1 = Math.min(getMinY(), newy);
        double y2 = Math.max(getMaxY(), newy);
        setRect(x1, y1, x2 - x1, y2 - y1);
}

Adds a point, specified by the double precision arguments newx and newy, to this Rectangle2D. The resulting Rectangle2D is the smallest Rectangle2D that contains both the original Rectangle2D and the specified point.

After adding a point, a call to contains with the added point as an argument does not necessarily return true. The contains method does not return true for points on the right or bottom edges of a rectangle. Therefore, if the added point falls on the left or bottom edge of the enlarged rectangle, contains returns false for that point.

 abstract public Rectangle2D createIntersection(Rectangle2D r)
Returns a new Rectangle2D object representing the
intersection of this Rectangle2D with the specified
Rectangle2D.

Returns a new Rectangle2D object representing the
union of this Rectangle2D with the specified

Determines whether or not the specified Object is equal to this Rectangle2D. The specified Object is equal to this Rectangle2D if it is an instance of Rectangle2D and if its location and size are the same as this Rectangle2D.

 public PathIterator getPathIterator(AffineTransform at) 
{
        return new RectIterator(this, at);
}

Returns an iteration object that defines the boundary of this Rectangle2D. The iterator for this class is multi-threaded safe, which means that this Rectangle2D class guarantees that modifications to the geometry of this Rectangle2D object do not affect any iterations of that geometry that are already in process.

 public PathIterator getPathIterator(AffineTransform at,
    double flatness) 
{
        return new RectIterator(this, at);
}

Returns an iteration object that defines the boundary of the flattened Rectangle2D. Since rectangles are already flat, the flatness parameter is ignored. The iterator for this class is multi-threaded safe, which means that this Rectangle2D class guarantees that modifications to the geometry of this Rectangle2D object do not affect any iterations of that geometry that are already in process.

Returns the hashcode for this Rectangle2D.

Intersects the pair of specified source Rectangle2D objects and puts the result into the specified destination Rectangle2D object. One of the source rectangles can also be the destination to avoid creating a third Rectangle2D object, but in this case the original points of this source rectangle will be overwritten by this method.
