Class DriverWrapperLW

java.lang.Object

org.postgresql.Driver

net.postgis.jdbc.DriverWrapper

net.postgis.jdbc.DriverWrapperLW

All Implemented Interfaces:

Driver

public class DriverWrapperLW
extends DriverWrapper

DriverWrapperLW 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 subclass always uses hex encoded EWKB as canonical text representation, and thus only works against PostGIS 1.x servers and newer. For usage notes, see DriverWrapper class, but use "jdbc:postgresql_lwgis:" as JDBC url prefix and net.postgis.jdbc.DriverWrapperLW as driver class.
