- All Superinterfaces:
EventListener
public interface ConnectionEventListener extends EventListener
An object that registers to be notified of events generated by a
PooledConnection
object.The
ConnectionEventListener
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 aConnectionEventListener
object when an application is finished using a pooled connection with which the listener has registered. The notification occurs after the application calls the methodclose
on its representation of aPooledConnection
object. AConnectionEventListener
is also notified when a connection error occurs due to the fact that thePooledConnection
is unfit for future use---the server has crashed, for example. The listener is notified by the JDBC driver just before the driver throws anSQLException
to the application using thePooledConnection
object.- Since:
- 1.4

Method Detail
connectionClosed
void connectionClosed(ConnectionEvent event)
Notifies thisConnectionEventListener
that the application has called the methodclose
on its representation of a pooled connection.- Parameters:
event
- an event object describing the source of the event
connectionErrorOccurred
void connectionErrorOccurred(ConnectionEvent event)
Notifies thisConnectionEventListener
that a fatal error has occurred and the pooled connection can no longer be used. The driver makes this notification just before it throws the application theSQLException
contained in the givenConnectionEvent
object.- Parameters:
event
- an event object describing the source of the event and containing theSQLException
that the driver is about to throw
