Method Detail

extend

public void extend(Iterator<Point> points)

Extend the current geometry with the given list of points.

Specified by:

extend in interface IGeometry

Parameters:

points - the points to add to the geometry.

extend

public void extend(Point[] points)

Extend the current geometry with the given list of points.

Specified by:

extend in interface IGeometry

Parameters:

points - the points to add to the geometry.

makePoints

public Point[] makePoints()

Make 100 new points along the contours of the existing path.

Points are evenly distributed according to the length of each geometric object.

Specified by:

makePoints in interface IGeometry

Returns:

a list of Points.

makePoints

public Point[] makePoints(int amount)

Description copied from interface: IGeometry

Make 100 new points along the contours of the existing path.

Points are evenly distributed according to the length of each geometric object.

Specified by:

makePoints in interface IGeometry

Parameters:

amount - the amount of points to distribute.

Returns:

a list of Points.

pointDelta

protected double pointDelta(int amount,
                            boolean closed)

Calculate how far the points would be apart, given the specified amount and whether the geometry is closed.

Parameters:

amount - the amount of points

closed - whether the geometry is closed

Returns:

the delta value between each point

pointAt

public abstract Point pointAt(double t)

clone

public abstract IGeometry clone()

Description copied from interface: IGeometry

Clone the geometry, returning a new copy that is totally independent from the original.

Specified by:

clone in interface Grob

Specified by:

clone in interface IGeometry

Specified by:

clone in class AbstractTransformable

Returns:

the new geometry object.

mapPoints

public abstract AbstractGeometry mapPoints(com.google.common.base.Function<Point,Point> pointFunction)

Change all points in the geometry and return a mutated copy. The original geometry remains unchanged.

Parameters:

pointFunction - The function to apply to each point.

Returns:

The new geometry.
