In fact the method createEventStateCollection() of
DelegatingObservationDispatcher is called by the VersionManagerImpl with
session parameter as null...
DelegatingObservationDispatcher:
public EventStateCollection createEventStateCollection(SessionImpl session,
Path pathPrefix) {
String userData = null;
try {
userData = ((ObservationManagerImpl)
session.getWorkspace().getObservationManager()).getUserData();
} catch (RepositoryException e) {
// should never happen because this
// implementation supports observation
}
return new EventStateCollection(this, session, pathPrefix, userData);
}
VersionManagerImpl$DynamicESCFactory :
public EventStateCollection createEventStateCollection(SessionImpl source) {
return obsMgr.createEventStateCollection(source,
VERSION_STORAGE_PATH);
}
VersionManagerImpl :
public void externalUpdate(ChangeLog changes, List events,
long timestamp, String userData)
throws RepositoryException {
EventStateCollection esc =
getEscFactory().createEventStateCollection(null);
esc.addAll(events);
esc.setTimestamp(timestamp);
esc.setUserData(userData);
sharedStateMgr.externalUpdate(changes, esc);
}
