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.
