Example 2 with RemoteEventCollection

use of org.apache.jackrabbit.rmi.remote.RemoteEventCollection in project jackrabbit by apache.

the class ClientEventPoll method run.

     * event listeners. This is how this method works:
     * <ol>
     * <li>Continue with next step if {@link #terminate()} has not been called
     * yet and the session is still alive.
     * <li>Call the {@link RemoteObservationManager#getNextEvent(long)} method
     * waiting for a specified time (5 seconds).
     * <li>If no event was received in the specified time go back to step #1.
     * <li>Extract the unique listener identifier from the remote event and
     * find it in the list of locally registered event listeners. Go back to
     * step #1 if no such listener exists.
     * <li>Convert the remote event list to an <code>EventIterator</code> and
     * call the <code>EventListener.onEvent()</code> method.
     * <li>Go back to step #1.
