Class GeoJSONPolygon

java.lang.Object

at.ac.ait.ariadne.routeformat.geojson.GeoJSONPolygon

All Implemented Interfaces:

GeoJSONGeometryObject, Validatable

public class GeoJSONPolygon
extends Object
implements GeoJSONGeometryObject

A polygon consisting of a mandatory exterior ring and optional interior rings defining holes. Note, that validate() does not check if the interior rings actually lie within the exterior ring.

public GeoJSONPolygon()

Method Detail

getCoordinates

public List<List<GeoJSONCoordinate>> getCoordinates()

Coordinates of a polygon are an array of LinearRing coordinate arrays (the first and the last coordinate must be the same, thereby closing the ring). The first element in the array represents the exterior ring. Any subsequent elements represent interior rings (or holes).

setCoordinates

public GeoJSONPolygon setCoordinates(List<List<GeoJSONCoordinate>> coordinates)

create

public static GeoJSONPolygon create(List<List<GeoJSONCoordinate>> points)

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface GeoJSONGeometryObject

Returns:

true if the element does not contain any coordinates

validate

public void validate()

Description copied from interface: Validatable

Checks if the instance is in a valid / useful state. If this is not the case an IllegalArgumentException including a description of the invalid state is thrown.

Specified by:

validate in interface Validatable

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toWKT

public String toWKT()

Specified by:

toWKT in interface GeoJSONGeometryObject

Returns:

the well known text representation of this geometry object

toString

public String toString()

Overrides:

toString in class Object
