DataSource (Apache Tomcat 7.0.67 API Documentation)

java.lang.Object
- org.apache.tomcat.jdbc.pool.DataSourceProxy
- - org.apache.tomcat.jdbc.pool.DataSource

All Implemented Interfaces:

java.sql.Wrapper, javax.management.MBeanRegistration, javax.sql.CommonDataSource, javax.sql.ConnectionPoolDataSource, javax.sql.DataSource, ConnectionPoolMBean, PoolConfiguration

Direct Known Subclasses:

XADataSource
```
public class DataSource
extends DataSourceProxy
implements javax.sql.DataSource, javax.management.MBeanRegistration, ConnectionPoolMBean, javax.sql.ConnectionPoolDataSource
```
A DataSource that can be instantiated through IoC and implements the DataSource interface since the DataSourceProxy is used as a generic proxy. The DataSource simply wraps a ConnectionPool in order to provide a standard interface to the user.
