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.
