public interface Domain2D
extends Shape2D

Interface for shapes that draws an 'interior' and an 'exterior'. An AbstractDomain2D can be defined with a non-self intersecting set of Curve2D, and contains all points lying 'on the left' of the parent curve.

Some Shape may seem very similar, for example Conic2D and ConicCurve2D. The reason is that a point can be contained in a Conic2D but not in the ConicCurve2D.

Method Detail

boundary

Boundary2D boundary()

Returns the boundary of the set. This boundary is either a continuous non intersecting curve (connected domain), or a set of non intersecting continuous curve (one continuous non-intersection for each connected part of the domain).

The returned curve is oriented, with an interior and an exterior.

Returns:

the boundary of the domain

contours

java.util.Collection<? extends Contour2D> contours()

Returns the set of contours that enclose this domain. The result is a collection of shapes that implement the Contour2D interface.

complement

Domain2D complement()

Returns the domain which complements this domain in the plane.

Returns:

the complement of this domain.

Since:

0.6.3

asPolygon

Polygon2D asPolygon(int n)

Returns an approximation of the domain as a polygon, or a MultiPolygon.

Returns:

a polygon

Since:

0.10.2

transform

Domain2D transform(AffineTransform2D transform)

Description copied from interface: Shape2D

Transforms the shape by an affine transform. Subclasses may override the type of returned shape.

Specified by:

transform in interface Shape2D

Parameters:

transform - an affine transform

Returns:

the transformed shape

clip

Domain2D clip(Box2D box)

Description copied from interface: Shape2D

Clip the shape with the given box, and returns a new shape. The box must be bounded.

Specified by:

clip in interface Shape2D

Parameters:

box - the clipping box

Returns:

the clipped shape

draw

fill

void fill(java.awt.Graphics2D g2)

Fills the interior of the domain, using the Graphics current Paint.

Parameters:

g2 - the Graphics to fill on

Since:
