Class GenericDomain2D

java.lang.Object
  math.geom2d.curve.GenericDomain2D

All Implemented Interfaces:

java.awt.Shape, Domain2D, Shape2D

public class GenericDomain2D
extends java.lang.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

getDistance

public double getDistance(java.awt.geom.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
