All Known Implementing Classes:

PointArray2D

public interface PointSet2D
extends PointShape2D, ShapeSet2D<Point2D>

A set of points. All points within the set are instances of Point2D. The most direct implementation of PointSet2D is PointArray2D.

Method Detail

add

boolean add(Point2D point)

Adds a new point to the point set. If point is not an instance of Point2D, a Point2D with same location is added instead of point.

Specified by:

add in interface ShapeSet2D<Point2D>

Parameters:

point - the initial point in the set

addAll

void addAll(java.util.Collection<? extends Point2D> points)

Add a series of points

Parameters:

points - an array of points

points

java.util.Collection<Point2D> points()

Returns the collection of points contained in this set.

Specified by:

points in interface PointShape2D

Returns:

the collection of points

size

int size()

Returns the number of points in the set.

Specified by:

size in interface PointShape2D

Specified by:

size in interface ShapeSet2D<Point2D>

Returns:

the number of points

transform

PointSet2D transform(AffineTransform2D trans)

Transforms the point set by returning a new point set containing each transformed point.

Specified by:

transform in interface PointShape2D

Specified by:

transform in interface Shape2D

Parameters:

trans - an affine transform

Returns:

the transformed shape

clip

PointSet2D clip(Box2D box)

Returns a new point set containing only points located within the box.

Specified by:

clip in interface PointShape2D

Specified by:

clip in interface Shape2D

Parameters:

box - the clipping box

Returns:

the clipped shape
