Interface GeoJson

All Superinterfaces:

java.io.Serializable

All Known Subinterfaces:

CoordinateContainer<T>, Geometry

All Known Implementing Classes:

Feature, FeatureCollection, GeometryCollection, LineString, MultiLineString, MultiPoint, MultiPolygon, Point, Polygon

public interface GeoJson
extends java.io.Serializable

Generic implementation for all GeoJson objects defining common traits that each GeoJson object has. This logic is carried over to Geometry which is an interface which all seven GeoJson geometries implement.

Method Summary

Modifier and Type	Method and Description
BoundingBox	bbox() A GeoJson object MAY have a member named "bbox" to include information on the coordinate range for its Geometries, Features, or FeatureCollections.
java.lang.String	toJson() This takes the currently defined values found inside the GeoJson instance and converts it to a GeoJson string.
java.lang.String	type() This describes the type of GeoJson geometry, Feature, or FeatureCollection this object is.

Method Detail

type

java.lang.String type()

This describes the type of GeoJson geometry, Feature, or FeatureCollection this object is. Every GeoJson Object will have this defined once an instance is created and will never return null.

Returns:

a String which describes the type of geometry, for this object it will always return Feature

toJson

java.lang.String toJson()

This takes the currently defined values found inside the GeoJson instance and converts it to a GeoJson string.

Returns:

a JSON string which represents this Feature

bbox

BoundingBox bbox()

A GeoJson object MAY have a member named "bbox" to include information on the coordinate range for its Geometries, Features, or FeatureCollections. The value of the bbox member MUST be an array of length 2*n where n is the number of dimensions represented in the contained geometries, with all axes of the most southwesterly point followed by all axes of the more northeasterly point. The axes order of a bbox follows the axes order of geometries.

Returns:

a double array with the length 2*n where n is the number of dimensions represented in the contained geometries
