Interface ConnectionEventListener

All Superinterfaces:: EventListener

public interface ConnectionEventListener
extends EventListener

A ConnectionEventListener is an object that registers to receive events generated by a PooledConnection.

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 ConnectionEventListener is notified by a JDBC driver when an application is finished using its Connection object. This event occurs after the application calls close on its representation of the PooledConnection. A ConnectionEventListener is also notified when a Connection error occurs due to the fact that the PooledConnection 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 SQLException to the application using the PooledConnection.

Method Summary

void connectionClosed(ConnectionEvent connectionEvent)
Invoked when the application calls close() on its representation of the connection.

void connectionErrorOccurred(ConnectionEvent connectionEvent)
Invoked when a fatal connection error occurs, just before an SQLException is thrown to the application.
