Constructor Detail

GeoJson

public GeoJson(IGeoCoordinates coordinates)

Constructor that sets the coordinates.

Parameters:

coordinates - a IGeoCoordinate implementing object that represents valid GeoJson coordinates

Method Detail

setCoordinates

public void setCoordinates(IGeoCoordinates coordinates)

Changes the coordinates of the GeoJson. The type is adjusted accordingly.

Parameters:

coordinates - a IGeoCoordinate implementing object that represents valid GeoJson coordinates

isValid

public boolean isValid()

Returns true if the GeoJson has coordinates.

Returns:

true, if the geo json has coordinates

getType

public String getType()

getCoordinates

public IGeoCoordinates getCoordinates()

clean

public void clean()

Attempts to detect and remove errors in a geoJson object, such as self-intersecting (multi-)polygons. Additionally, MultiPolygons that can be simplified, may become regular Polygons. If the coordinates are broken beyond all repair, they will become null, rendering the GeoJson invalid.
