Method Detail

addEventListener

void addEventListener(long listenerId,
                      int eventTypes,
                      String absPath,
                      boolean isDeep,
                      String[] uuid,
                      String[] nodeTypeName,
                      boolean noLocal)
               throws RepositoryException,
                      RemoteException

Deprecated.

Remote version of the ObservationManager.addEventListener() method. See class comment for an explanation on how the listenerId is used.

Parameters:

listenerId - The identification of the listener on the client side to which events will be directed.

eventTypes - The mask of event types to be sent to this listener.

absPath - The root item defining a subtree for which events are to be delivered.

isDeep - true if the events from the complete subtree rooted at absPath are to be sent or only for the item at the given path.

uuid - An optional list of node UUIDs for which events are to be sent. If null this parameter is ignored.

nodeTypeName - An optional list of node type names for which events are to be sent. If null this parameter is ignored.

noLocal - true if only events are to be sent which do not originate from the session to which this instance belongs.

Throws:

RepositoryException - on repository errors

RemoteException - on RMI errors

removeEventListener

void removeEventListener(long listenerId)
                  throws RepositoryException,
                         RemoteException

Deprecated.

Remote version of the ObservationManager.removeEventListener() method. See class comment for an explanation on how the listenerId is used.

Parameters:

listenerId - The identification of the listener on the client side to which events will be directed.

Throws:

RepositoryException - on repository errors

RemoteException - on RMI errors

getNextEvent

RemoteEventCollection getNextEvent(long timeout)
                            throws RemoteException

Deprecated.

Returns the next event to be dispatched to registered event listeners. If no event is available, this method blocks until one is available or until the given timeout expires.

Parameters:

timeout - The time in milliseconds to wait for the next event available to be dispatched. If negative or zero, this method waits for ever.

Returns:

The RemoteEventCollection to be dispatched. null is returned if the method timed out waiting for an event to be dispatched.

Throws:

RemoteException - on RMI errors
