Constructor Detail

DataSourceConnectionFactory

public DataSourceConnectionFactory(DataSource datasource,
                                   boolean useProxies)

Constructs a new DataSourceConnectionFactory with given name, engine, mapping and datasource. Factory will be ready to use without calling initialize first.

Parameters:

datasource - The preconfigured datasource to use for creating connections.

useProxies - Wrap JDBC connections by proxies?

DataSourceConnectionFactory

public DataSourceConnectionFactory(DataSource dataSource,
                                   boolean useProxies,
                                   ClassLoader loader)

Constructs a new DataSourceConnectionFactory with given database and mapping. Initialize needs to be called before using the factory to create connections.

Parameters:

dataSource - DataSouce configuration.

useProxies - Wrap JDBC connections by proxies?

loader - ClassLoader to use.

Method Detail

loadDataSource

public static DataSource loadDataSource(DataSource confDataSource,
                                        ClassLoader loader)
                                 throws MappingException

Initialize JDBC DataSource instance with the given database configuration instances and the given class loader.

Parameters:

confDataSource - DataSource configuration.

loader - ClassLoader to use.

Returns:

The initialized DataSource.

Throws:

MappingException - Problem related to analysing the JDO configuration.

setParameters

public static void setParameters(DataSource dataSource,
                                 Param[] params)
                          throws MappingException

Set all the parameters of the given array at the given datasource by calling one of the set methods of the datasource.

Parameters:

dataSource - The datasource to set the parameters on.

params - The parameters to set on the datasource.

Throws:

MappingException - If one of the parameters could not be set.

buildMethodName

public static String buildMethodName(String name)

Build the name of the method to set the parameter value of the given name. The name of the method is build by preceding given parameter name with 'set' followed by all letters of the name. In addition the first letter and all letters following a '-' sign are converted to upper case.

Parameters:

name - The name of the parameter.

Returns:

The name of the method to set the value of this parameter.

initializeFactory

public void initializeFactory()
                       throws MappingException

Initialize the concrete factory.

Specified by:

initializeFactory in interface ConnectionFactory

Throws:

MappingException - If concrete factory could not be initialized.

createConnection

public Connection createConnection()
                            throws SQLException

Creates a new JDBC Connection instance.

Specified by:

createConnection in interface ConnectionFactory

Returns:

A JDBC Connection.

Throws:

SQLException - If the JDBC connection cannot be created.
