Class Geometry

java.lang.Object

io.debezium.data.geometry.Geometry

Direct Known Subclasses:

Geography, Point

public class Geometry
extends Object

A semantic type for an OGC Simple Features for SQL Geometry. Used to describe geometries on a planar basis (rather than Geography, which is a spherical basis).

See the Open Geospatial Consortium Simple Features Access specification for details on the Well-Known-Binary format http://www.opengeospatial.org/standards/sfa

WKB has to be forwards-compatible to the spec, so strict OGC WKB, and EWKB (PostGIS) are both ok.

Method Detail

builder

public static org.apache.kafka.connect.data.SchemaBuilder builder()

Returns a SchemaBuilder for a Geometry field. You can use the resulting SchemaBuilder to set additional schema settings such as required/optional, default value, and documentation.

Returns:

the schema builder

schema

public static org.apache.kafka.connect.data.Schema schema()

Returns a SchemaBuilder for a Geometry field, with all other default Schema settings.

Returns:

the schema

createValue

public static org.apache.kafka.connect.data.Struct createValue(org.apache.kafka.connect.data.Schema geomSchema,
                                                               byte[] wkb,
                                                               Integer srid)

Create a value for this schema using WKB and SRID

Parameters:

geomSchema - a Schema instance which represents a geometry; may not be null

wkb - OGC Well-Known Binary representation of the geometry; may not be null

srid - the coordinate reference system identifier; may be null if unset/unknown

Returns:

a Struct which represents a Connect value for this schema; never null
