Constructor Detail

Polygon

protected Polygon(JSObject element)

Polygon

public Polygon(LinearRing[] rings)

Method Detail

narrowToPolygon

public static Polygon narrowToPolygon(JSObject polygon)

getComponents

public LinearRing[] getComponents()

Polygons are composed of LinearRing geometries. LinearRing geometries are MultiPoint geometries, whose components are Points. The first and last component of a LinearRing is the same point, even if a LinearRing is instantiated with an array of Points whose first and last point are not the same.

Returns:

Array of LinearRing Objects

intersects

public boolean intersects(Geometry geometry)

Determine if the input geometry intersects this one.

Parameters:

geometry - Any type of geometry.

Returns:

The input geometry intersects this one.

getArea

public double getArea()

Overrides:

getArea in class Geometry

getGeodesicArea

public double getGeodesicArea(Projection projection)
