Method Detail

getVertices

Collection<Point2D> getVertices()

Returns the vertices (singular points) of the polygon

getVertex

Point2D getVertex(int i)

Returns the i-th vertex of the polygon.

Parameters:

i - index of the vertex, between 0 and the number of vertices

getVertexNumber

int getVertexNumber()

Returns the number of vertices of the polygon

Since:

0.6.3

getEdges

Collection<? extends LineSegment2D> getEdges()

Return the edges as line segments of the polygon

getEdgeNumber

int getEdgeNumber()

Returns the number of edges of the polygon

getRings

Collection<? extends LinearRing2D> getRings()

Returns the set of rings comprising the boundary of this polygon.

Returns:

the set of boundary rings.

getBoundary

CirculinearBoundarySet2D<? extends LinearRing2D> 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 CirculinearDomain2D

Specified by:

getBoundary in interface Domain2D

Returns:

the boundary of the domain

transform

Polygon2D transform(AffineTransform2D trans)

Returns the new Polygon created by an affine transform of this polygon.

Specified by:

transform in interface Domain2D

Specified by:

transform in interface Shape2D

Parameters:

trans - an affine transform

Returns:

the transformed shape

complement

Polygon2D complement()

Returns the complementary polygon.

Specified by:

complement in interface Domain2D

Returns:

the polygon complementary to this
