Interface Geometry

All Known Subinterfaces:

LineString, Point, Polygon

public interface Geometry

The driver-side representation for a DSE geospatial type.

     Row row = dseSession.execute("SELECT coords FROM points_of_interest WHERE name = 'Eiffel Tower'").one();
     Point coords = row.get("coords", Point.class);
 

The default implementations returned by the driver are immutable and serializable. If you write your own implementations, they should at least be thread-safe; serializability is not mandatory, but recommended for use with some 3rd-party tools like Apache Spark ™.

Method Summary

Modifier and Type	Method and Description
String	asGeoJson() Returns a JSON representation of this geospatial type.
ByteBuffer	asWellKnownBinary() Returns a Well-known Binary (WKB) representation of this geospatial type.
String	asWellKnownText() Returns a Well-known Text (WKT) representation of this geospatial type.
boolean	contains(Geometry other) Tests whether this geospatial type instance contains another instance.

Method Detail

asWellKnownText

@NonNull
String asWellKnownText()

Returns a Well-known Text (WKT) representation of this geospatial type.

asWellKnownBinary

@NonNull
ByteBuffer asWellKnownBinary()

Returns a Well-known Binary (WKB) representation of this geospatial type.

Note that, due to DSE implementation details, the resulting byte buffer always uses little-endian order, regardless of the platform's native order.

asGeoJson

@NonNull
String asGeoJson()

Returns a JSON representation of this geospatial type.

contains

boolean contains(@NonNull
                 Geometry other)

Tests whether this geospatial type instance contains another instance.

Parameters:

other - the other instance.

Returns:

whether this contains other.
