| * <P> |
| * The <code>ConnectionEventListener</code> interface is implemented by a |
| * connection pooling component. A connection pooling component will |
| * usually be provided by a JDBC driver vendor or another system software |
| * vendor. A JDBC driver notifies a <code>ConnectionEventListener</code> |
| * object when an application is finished using a pooled connection with |
| * which the listener has registered. The notification |
| * occurs after the application calls the method <code>close</code> on |
| * its representation of a <code>PooledConnection</code> object. A |
| * <code>ConnectionEventListener</code> is also notified when a |
| * connection error occurs due to the fact that the <code>PooledConnection</code> |
| * is unfit for future use---the server has crashed, for example. |
| * The listener is notified by the JDBC driver just before the driver throws an |
| * <code>SQLException</code> to the application using the |
| * <code>PooledConnection</code> object. |
| * |
| * @since 1.4 |
