public interface JackrabbitObservationManager
void addEventListener(EventListener listener, JackrabbitEventFilter filter) throws RepositoryException
In addition to the
EventFilter, the set of events reported
will be further filtered by the access rights of the
JackrabbitEventFilter for a description of the filtering parameters available.
The filter of an already-registered
EventListener can be
changed at runtime by re-registering the same
object (i.e. the same actual Java object) with a new filter.
The implementation must ensure that no events are lost during the changeover.
In addition to the filters placed on a listener above, the scope of
observation support, in terms of which parts of a workspace are observable, may also
be subject to implementation-specific restrictions. For example, in some
repositories observation of changes in the
subgraph may not be supported.
RepositoryException- If an error occurs.
