Class Geometry

java.lang.Object

com.datastax.driver.dse.geometry.Geometry

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

Distance, LineString, Point, Polygon

public abstract class Geometry
extends Object
implements Serializable

The driver-side representation for a DSE geospatial type.

DseCluster.Builder registers codecs for those types, so that they can be used transparently in queries:

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

     dseSession.execute("INSERT INTO points_of_interest (name, coords) VALUES (?, ?)",
             "Washington Monument", new Point(38.8895, 77.0352));

Method Detail

asWellKnownText

public String asWellKnownText()

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

Returns:

a Well-known Text representation of this object.

asWellKnownBinary

public 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.

Returns:

a Well-known Binary representation of this object.

asGeoJson

public String asGeoJson()

Returns a JSON representation of this geospatial type.

Returns:

a JSON representation of this object.

contains

public boolean contains(Geometry other)

Tests whether this geospatial type instance contains another instance.

Parameters:

other - the other instance.

Returns:

whether this contains other.

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
