package org.apache.commons.configuration.event;
21
* An event listener interface to be implemented by observers that are
22
* interested in internal errors caused by processing of configuration
26
* Some configuration classes use an underlying storage where each access of a
27
* property can cause an exception. In earlier versions of this library such
28
* exceptions were typically ignored. By implementing this interface and
29
* registering at a configuration object as an error listener it is now possible
30
* for clients to receive notifications about those internal problems.
