com.datastax.driver.dse.geometry.Geometry

com.datastax.driver.dse.geometry.Point

All Implemented Interfaces:

Serializable

public class Point
extends Geometry

The driver-side representation of DSE's PointType.

This is a zero-dimensional object that represents a specific (X,Y) location in a two-dimensional XY-plane. In case of Geographic Coordinate Systems, the X coordinate is the longitude and the Y is the latitude.

Constructor Detail

Point

public Point(double x,
             double y)

Creates a new point.

Parameters:

x - the X coordinate (or its longitude in Geographic Coordinate Systems).

y - the Y coordinate (or its latitude in Geographic Coordinate Systems).

Method Detail

fromWellKnownText

public static Point fromWellKnownText(String source)

Creates a point from its Well-known Text (WKT) representation.

Parameters:

source - the Well-known Text representation to parse.

Returns:

the point represented by the WKT.

Throws:

InvalidTypeException - if the string does not contain a valid Well-known Text representation.

fromWellKnownBinary

public static Point fromWellKnownBinary(ByteBuffer source)

Creates a point from its Well-known Binary (WKB) representation.

Parameters:

source - the Well-known Binary representation to parse.

Returns:

the point represented by the WKB.

Throws:

InvalidTypeException - if the provided ByteBuffer does not contain a valid Well-known Binary representation.

fromGeoJson

public static Point fromGeoJson(String source)

Creates a point from a GeoJSON Point representation.

Parameters:

source - the GeoJSON Point representation to parse.

Returns:

the point represented by the GeoJSON Point.

Throws:

InvalidTypeException - if the string does not contain a valid GeoJSON Point representation.

X

public double X()

Returns the X coordinate of this 2D point (or its longitude in Geographic Coordinate Systems.

Returns:

the X coordinate.

Y

public double Y()

Returns the Y coordinate of this 2D point (or its latitude in Geographic Coordinate Systems).

Returns:

the Y coordinate.
