Method Summary

void	close() A hook which is called when the resources of the associated DataSource can be released.
javax.sql.DataSource	getDataSource()

Method Detail

getDataSource

public javax.sql.DataSource getDataSource()
                                   throws TorqueException

Returns:

the DataSource configured by the factory.

Throws:

TorqueException - if the source can't be returned

initialize

public void initialize(org.apache.commons.configuration.Configuration configuration)
                throws TorqueException

Initialize the factory.

Parameters:

configuration - where to load the factory settings from

Throws:

TorqueException - Any exceptions caught during processing will be rethrown wrapped into a TorqueException.

setSchema

public void setSchema(java.lang.String schema)

Deprecated. use DatabaseInfo.setSchema() instead. Will be removed in a future version of Torque.

Sets the current schema for the database connection

Parameters:

schema - The current schema name

getSchema

public java.lang.String getSchema()

Deprecated. use DatabaseInfo.getSchema() instead. Will be removed in a future version of Torque.

This method returns the current schema for the database connection

Returns:

The current schema name. Null means, no schema has been set.

Throws:

TorqueException - Any exceptions caught during processing will be rethrown wrapped into a TorqueException.

close

public void close()
           throws TorqueException

A hook which is called when the resources of the associated DataSource can be released. After close() is called, the other methods may not work any more (e.g. getDataSource() might return null). It is not guaranteed that this method does anything. For example, we do not want to close connections retrieved via JNDI, so the JndiDataSouurceFactory does not close these connections

Throws:

TorqueException - Any exceptions caught during processing will be rethrown wrapped into a TorqueException.
