Class GenericDomain2D

java.lang.Object
  math.geom2d.domain.GenericDomain2D

All Implemented Interfaces:

Serializable, Domain2D, Shape2D

Direct Known Subclasses:

GenericCirculinearDomain2D

public class GenericDomain2D
extends Object
implements Domain2D

A domain defined from its boundary. The boundary curve must be correctly oriented, non self intersecting, and clearly separating interior and exterior.

All contains and intersect tests are computed from the signed distance of the boundary curve.

public GenericDomain2D(Boundary2D boundary)

Method Detail

getBoundary

public Boundary2D getBoundary()

Description copied from interface: Domain2D

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.

Specified by:

getBoundary in interface Domain2D

Returns:

the boundary of the domain

complement

public Domain2D complement()

Description copied from interface: Domain2D

Returns the domain which complements this domain in the plane.

Specified by:

complement in interface Domain2D

Returns:

the complement of this domain.

getDistance

public double getDistance(Point2D p)

Description copied from interface: Shape2D

get the distance of the shape to the given point, or the distance of point to the frontier of the shape in the case of a plain shape.

Specified by:

getDistance in interface Shape2D

getDistance

public double getDistance(double x,
                          double y)

Description copied from interface: Shape2D

get the distance of the shape to the given point, specified by x and y, or the distance of point to the frontier of the shape in the case of a plain (i.e. fillable) shape.

Specified by:

getDistance in interface Shape2D

isBounded

public boolean isBounded()

Returns true if the domain is bounded. The domain is unbounded if either its boundary is unbounded, or a point located outside of the boundary bounding box is located inside of the domain.

Specified by:

isBounded in interface Shape2D

isEmpty

public boolean isEmpty()

Description copied from interface: Shape2D

Returns true if the shape does not contain any point. This is the case for example for PointSet2D without any point.

Specified by:

isEmpty in interface Shape2D

Returns:

true if the shape does not contain any point.

clip

public 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 Domain2D

Specified by:

clip in interface Shape2D

Parameters:

box - the clipping box

Returns:

the clipped shape

getBoundingBox

public Box2D getBoundingBox()

If the domain is bounded, returns the bounding box of its boundary, otherwise returns an infinite bounding box.

Specified by:

getBoundingBox in interface Shape2D

Returns:

the bounding box of the shape.

transform

public GenericDomain2D transform(AffineTransform2D trans)

Returns a new domain which is created from the transformed domain of this boundary.

Specified by:

transform in interface Domain2D

Specified by:

transform in interface Shape2D

Parameters:

trans - an affine transform

Returns:

the transformed shape

contains

public boolean contains(double x,
                        double y)

Description copied from interface: Shape2D

Checks if the shape contains the planar point defined by (x,y).

Specified by:

contains in interface Shape2D

contains

public boolean contains(Point2D p)

Description copied from interface: Shape2D

Checks if the shape contains the given point.

Specified by:

contains in interface Shape2D

draw

public void draw(Graphics2D g2)

Description copied from interface: Domain2D

Draws the boundary of the domain, using current Stroke and color.

Specified by:

draw in interface Domain2D

Specified by:

draw in interface Shape2D

Parameters:

g2 - the Graphics to draw on
