Class DriverWrapperAutoprobe

java.lang.Object

org.postgresql.Driver

org.postgis.DriverWrapper

org.postgis.DriverWrapperAutoprobe

All Implemented Interfaces:

java.sql.Driver

public class DriverWrapperAutoprobe
extends DriverWrapper

DriverWrapperAutoprobe Wraps the PostGreSQL Driver to transparently add the PostGIS Object Classes. This avoids the need of explicit addDataType() calls from the driver users side. This DriverWrapper tries to autoprobe the installed PostGIS version to decide whether to use EWKT or hex encoded EWKB as canonical text representation. It uses the first PostGIS installation found in your namespace search path (aka schema search path) on the server side, and this works as long as you do not access incompatible PostGIS versions that reside in other schemas. For usage notes, see DriverWrapper class, but use "jdbc:postgresql_autogis:" as JDBC url prefix and org.postgis.DriverWrapperAutoprobe as driver class.
