package javax.naming.event;

/**
  * Specifies the method that a listener of a {@code NamingEvent}
  * with event type of {@code OBJECT_CHANGED} must implement.
  *<p>
  * An {@code OBJECT_CHANGED} event type is fired when (the contents of)
  * an object has changed. This might mean that its attributes have been modified,
  * added, or removed, and/or that the object itself has been replaced.
  * How the object has changed can be determined by examining the
  * {@code NamingEvent}'s old and new bindings.
  *<p>
  * A listener interested in {@code OBJECT_CHANGED} event types must:
  *<ol>
  *
  *<li>Implement this interface and its method ({@code objectChanged()})
  *<li>Implement {@code NamingListener.namingExceptionThrown()} so that
  * it will be notified of exceptions thrown while attempting to
  * collect information about the events.
  *<li>Register with the source using the source's {@code addNamingListener()}
  *    method.
  *</ol>
  * A listener that wants to be notified of namespace change events
  * should also implement the {@code NamespaceChangeListener}
  * interface.
