Constructor Detail

CompositeGeometry

public CompositeGeometry()

Method Detail

toJsonMap

public abstract Map toJsonMap()

Creates a Map that mimics the GeoJSON structure.

Throws:

UnsupportedOperationException - when the object cannot write into the map

toWkt

public abstract String toWkt()

Returns:

well-known text of underlying equivalent Geometric object

toGeoRssPositions

public abstract List<org.apache.abdera.ext.geo.Position> toGeoRssPositions()

getGeometry

public abstract com.vividsolutions.jts.geom.Geometry getGeometry()

Returns:

equivalent geometric object

getCompositeGeometry

public static CompositeGeometry getCompositeGeometry(com.vividsolutions.jts.geom.Geometry geometry)

Deciphers the CompositeGeometry object to return based on Geometry

Parameters:

geometry -

Returns:

CompositeGeometry

getCompositeGeometry

public static CompositeGeometry getCompositeGeometry(String type,
                                                     Map jsonObject)

Parameters:

type - case-sensitive String of the geometric type, must match the exact spelling in the GeoJSON standard (geojson.org)

jsonObject - Map of coordinates or geometries

Returns:

CompositeGeometry based on the type passed in, returns null if the type is not one of the standard GeoJSON geometric strings.

getCoordinate

protected static com.vividsolutions.jts.geom.Coordinate getCoordinate(List primitiveCoordinates)

Parameters:

primitiveCoordinates - requires x and y coordinate information as a List, x coordinate is the first item in the list

Returns:

Coordinate object

getCoordinates

protected static com.vividsolutions.jts.geom.Coordinate[] getCoordinates(List<List<String>> primitiveCoordinatesList)

Parameters:

primitiveCoordinatesList - a List of [x,y] coordinates. The [x,y] coordinates is a list of two objects where x coordinate is first and the y coordinate is second in the list

Returns:

an array of Coordinate objects, if input is null or empty, it will return an empty array
