Class Polyline

java.lang.Object
  com.partnersoft.v3x.geometry.single.Polyline

public class Polyline
extends java.lang.Object

A single, FloatBuffer-based polyline.

Field Summary

FloatBuffer

coords

Constructor Summary

Polyline()

Polyline(FloatBuffer buffy)

Polyline(int size)

Polyline(Polyline copyThis)

Method Summary

PolylineArray	clipOutRectangle(float x, float y, float width, float height) Clips a rectangle out of the polyline to a rectangle, producing zero or more resultant polylines that are outside the rectangle.
PolylineArray	clipOutRectangle(Rectangle rectangle)
void	clipOutRectangle(Rectangle rectangle, PolylineArray results) This is the fastest public clipOutRectangle variation - passing a reuseable PolylineArray can reduce allocation overhead.
PolylineArray	clipOutRectangles(Rectangle[] rectangles) Cuts a collection of rectangular holes out.
Point	getCentroid()
Rectangle	getExtents()
float	getLength()
void	reduceDetail(float granularity)
static void	reduceDetail(FloatBuffer coords, float granularity) Attempts to reduce the complexity of the line by eliminating points which add nothing to the detail at a certain granularity.
java.lang.String	toString()

reduceDetail

public static final void reduceDetail(FloatBuffer coords,
                                      float granularity)

Attempts to reduce the complexity of the line by eliminating points which add nothing to the detail at a certain granularity. Granularity is defined as a discretizing parameter - it sets up a grid of that cell size and points which fall into the same grid cell are regarded as identical.

getCentroid

public final Point getCentroid()

getLength

public final float getLength()

getExtents

public final Rectangle getExtents()

clipOutRectangle

public final PolylineArray clipOutRectangle(float x,
                                            float y,
                                            float width,
                                            float height)

Clips a rectangle out of the polyline to a rectangle, producing zero or more resultant polylines that are outside the rectangle.

clipOutRectangle

public final PolylineArray clipOutRectangle(Rectangle rectangle)

clipOutRectangle

public final void clipOutRectangle(Rectangle rectangle,
                                   PolylineArray results)

This is the fastest public clipOutRectangle variation - passing a reuseable PolylineArray can reduce allocation overhead. The others eventually call this.

clipOutRectangles

public final PolylineArray clipOutRectangles(Rectangle[] rectangles)

Cuts a collection of rectangular holes out.
