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
