Field Details

UNKNOWN_ENVELOPE

private static final double[] UNKNOWN_ENVELOPE

typeAndDimensionSystem

private final int typeAndDimensionSystem

Geometry type and dimension system in OGC geometry code format (type + dimensionSystem * 1000).

srid

private final int srid

Spatial reference system identifier.

envelope

private double[] envelope

The envelope of the value. Calculated only on request.

geometry

private Object geometry

The value. Converted from WKB only on request as conversion from/to WKB cost a significant amount of CPU cycles.

Constructor Details

ValueGeometry

private ValueGeometry(byte[] bytes,
 double[] envelope)

Create a new geometry object.

Parameters:

bytes - the EWKB bytes

envelope - the envelope

Method Details

getFromGeometry

public static ValueGeometry getFromGeometry(Object o)

Get or create a geometry value for the given geometry.

Parameters:

o - the geometry object (of type org.locationtech.jts.geom.Geometry)

Returns:

the value

get

public static ValueGeometry get(String s)

Get or create a geometry value for the given geometry.

Parameters:

s - the WKT or EWKT representation of the geometry

Returns:

the value

get

public static ValueGeometry get(byte[] bytes)

Get or create a geometry value for the given internal EWKB representation.

Parameters:

bytes - the WKB representation of the geometry. May not be modified.

Returns:

the value

getFromEWKB

public static ValueGeometry getFromEWKB(byte[] bytes)

Get or create a geometry value for the given EWKB value.

Parameters:

bytes - the WKB representation of the geometry

Returns:

the value

fromEnvelope

public static Value fromEnvelope(double[] envelope)

Creates a geometry value for the given envelope.

Parameters:

envelope - envelope. May not be modified.

Returns:

the value

getGeometry

public org.locationtech.jts.geom.Geometry getGeometry()

Get a copy of geometry object. Geometry object is mutable. The returned object is therefore copied before returning.

Returns:

a copy of the geometry object

getTypeAndDimensionSystem

public int getTypeAndDimensionSystem()

Returns geometry type and dimension system in OGC geometry code format (type + dimensionSystem * 1000).

Returns:

geometry type and dimension system

getGeometryType

public int getGeometryType()

Returns geometry type.

Returns:

geometry type and dimension system

getDimensionSystem

public int getDimensionSystem()

Return a minimal dimension system that can be used for this geometry.

Returns:

dimension system

getSRID

public int getSRID()

Return a spatial reference system identifier.

Returns:

spatial reference system identifier

getEnvelopeNoCopy

public double[] getEnvelopeNoCopy()

Return an envelope of this geometry. Do not modify the returned value.

Returns:

envelope of this geometry

intersectsBoundingBox

public boolean intersectsBoundingBox(ValueGeometry r)

Test if this geometry envelope intersects with the other geometry envelope.

Parameters:

r - the other geometry

Returns:

true if the two overlap

getEnvelopeUnion

public Value getEnvelopeUnion(ValueGeometry r)

Get the union.

Parameters:

r - the other geometry

Returns:

the union of this geometry envelope and another geometry envelope
