public class CoordinateSystemModifiedEPSGFactory

extends CoordinateSystemEPSGFactory

An EPSG factory which replaces some table or column names by other names. This factory is used for EPSG database backed by an other software than MS-Access. This class overrides adaptSQL(java.lang.String) to change the SQL statements so they are suitable for non-ms access versions of EPSG databases (version 6.4). By default, the new SQL statements use the new table and field names in the Data Description Language (DDL) scripts provided in version 6.4 to create the schema for the database. Subclasses can changes this default behavior by modifying the map.

In order to register this ANSI version as the default EPSG factory, invokes the following only once from the command line. The change will by system-wide:

 java org.geotools.cs.CoordinateSystemEPSGFactory -implementation=org.geotools.cs.CoordinateSystemModifiedEPSGFactory

Constructor Detail

CoordinateSystemModifiedEPSGFactory

public CoordinateSystemModifiedEPSGFactory(CoordinateSystemFactory factory,
                                           java.sql.Connection connection)

Deprecated.

Construct an authority factory using the specified connection.

Parameters:

factory - The underlying factory used for objects creation.

connection - The connection to the underlying EPSG database.

CoordinateSystemModifiedEPSGFactory

public CoordinateSystemModifiedEPSGFactory(CoordinateSystemFactory factory,
                                           java.lang.String url,
                                           java.lang.String driver)
                                    throws java.sql.SQLException

Deprecated.

Construct an authority factory using the specified URL to an EPSG database.

Parameters:

factory - The underlying factory used for objects creation.

url - The url to the EPSG database. For example, a connection to postgresql may have an URL like "jdbc:postgresql://localhost/epsg?user=<user>&pass=<password>".

driver - An optional driver to load, or null if none. This is a convenience argument for the following pseudo-code:

Class.forName(driver).newInstance();

A message is logged to "org.geotools.cts" stating if the loading succeeded of failed. For postgresql, a typical value for this argument is "org.postgresql.Driver". This argument needs to be non-null only once for a specific driver.

Throws:

java.sql.SQLException - if the constructor failed to connect to the EPSG database.

Method Detail

adaptSQL

protected java.lang.String adaptSQL(java.lang.String statement)

Deprecated.

Modifies the given SQL string to be suitable for non-ms access databases. This replaces table and field names in the SQL with the new names in the SQL DDL scripts provided with version 6.4 of the EPSG database.

Overrides:

adaptSQL in class CoordinateSystemEPSGFactory

Parameters:

statement - The statement in MS-Access syntax.

Returns:

The SQL statement to use, suitable for a non-ms access database.
