getColumnMapper

public ColumnMapper<org.locationtech.jts.geom.Geometry> getColumnMapper()

Description copied from interface: Codec

Returns a ColumnMapper that creates an attribute value from a database column.

Either this method or Codec.getColumnMapper(ConfigRegistry) must be implemented.

Specified by:

getColumnMapper in interface Codec<org.locationtech.jts.geom.Geometry>

getArgumentFunction

public Function<org.locationtech.jts.geom.Geometry,Argument> getArgumentFunction()

Description copied from interface: Codec

Returns a Function that creates an Argument to map an attribute value onto the database column.

Either this method or Codec.getArgumentFunction(ConfigRegistry) must be implemented.

Specified by:

getArgumentFunction in interface Codec<org.locationtech.jts.geom.Geometry>

serialize

private static byte[] serialize(org.locationtech.jts.geom.Geometry geometry)

Serializes a geometry in the WKB format.

Parameters:

geometry - An Geometry object or one of its subclasses. May be null.

Returns:

A byte array representing the Geometry object in WKB format or null if the object was null.

deserialize

private static org.locationtech.jts.geom.Geometry deserialize(byte[] bytes)

Deserializes a geometry in the WKB format.

Parameters:

bytes - A byte array representing a Geometry in WKB format or null.

Returns:

The deserialized object or null if the byte array was null.

hexStringToByteArray

private static byte[] hexStringToByteArray(String s)
