Class DataSource

java.lang.Object

org.apache.tomcat.jdbc.pool.DataSourceProxy

org.apache.tomcat.jdbc.pool.DataSource

All Implemented Interfaces:

Wrapper, MBeanRegistration, CommonDataSource, ConnectionPoolDataSource, DataSource, ConnectionPoolMBean, PoolConfiguration

Direct Known Subclasses:

XADataSource

public class DataSource
extends DataSourceProxy
implements DataSource, MBeanRegistration, ConnectionPoolMBean, 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.
