Interface XQConnectionEventListener

public interface XQConnectionEventListener

An object that registers to be notified of events generated by a PooledXQConnection object.

The XQConnectionEventListener interface is implemented by a connection pooling component. A connection pooling component will usually be provided by an XQJ vendor or by another system software vendor. An XQJ implementation notifies an XQConnectionEventListener 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 close on its representation of a PooledXQConnection object. An XQConnectionEventListener is also notified when a connection error occurs due to the fact that the PooledXQConnection is unfit for future use - the network connection to the XML datasource died, for example. The listener is notified by the XQJ implementation just before it throws an XQException to the application using the PooledXQConnection object.

Method Summary

void	connectionClosed(XQConnectionEvent event) Notifies this XQConnectionEventListener that the application has called the method close on its representation of a pooled connection.
void	connectionErrorOccurred(XQConnectionEvent event) Notifies this XQConnectionEventListener that a fatal error has occurred and the pooled connection can no longer be used.

Method Detail

connectionClosed

void connectionClosed(XQConnectionEvent event)

Notifies this XQConnectionEventListener that the application has called the method close on its representation of a pooled connection.

Parameters:

event - an event object describing the source of the event

connectionErrorOccurred

void connectionErrorOccurred(XQConnectionEvent event)

Notifies this XQConnectionEventListener that a fatal error has occurred and the pooled connection can no longer be used. The XQJ implementation makes this notification just before it throws the application the XQException contained in the given XQConnectionEvent object.

Parameters:

event - an event object describing the source of the event and containing the XQException that the XQJ implementation will throw
