gov.nasa.worldwind.render.ContourLine

gov.nasa.worldwind.render.ContourLinePolygon

All Implemented Interfaces:

Renderable

public class ContourLinePolygon
extends ContourLine

Renders a contour line on the terrain at a given elevation. The controur line extent is bounded by a polygon defined by a list of LatLon.

Method Summary

Modifier and Type	Method	Description
protected java.util.ArrayList<Intersection>	filterIntersections(DrawContext dc, java.util.ArrayList<Intersection> list)	Filters the given intersection segments list according to some criteria - here the inclusion inside the current polygon.
java.util.List<? extends LatLon>	getPositions()	Get the list of LatLon that describe the current bounding polygon.
void	setPositions(java.util.ArrayList<? extends LatLon> positions)	Set the list of LatLon that describes a closed polygon - one which last position is equal to the first, used to delineate the extent of the contour line.

Method Detail

getPositions

public java.util.List<? extends LatLon> getPositions()

Get the list of LatLon that describe the current bounding polygon.

Returns:

the list of LatLon that describe the current bounding polygon.

setPositions

public void setPositions(java.util.ArrayList<? extends LatLon> positions)

Set the list of LatLon that describes a closed polygon - one which last position is equal to the first, used to delineate the extent of the contour line.

Parameters:

positions - the list of LatLon that describe a closed polygon.

Throws:

java.lang.IllegalArgumentException - if positions is null.

filterIntersections

protected java.util.ArrayList<Intersection> filterIntersections(DrawContext dc,
                                                                java.util.ArrayList<Intersection> list)

Filters the given intersection segments list according to some criteria - here the inclusion inside the current polygon.

Overrides:

filterIntersections in class ContourLine

Parameters:

dc - the current DrawContext

list - the list of Intersection to be filtered.

Returns:

the filtered list.
