Examples with EventFilter org.apache.jackrabbit.spi.EventFilter used on opensource projects

Example 1 with EventFilter

use of org.apache.jackrabbit.spi.EventFilter in project jackrabbit by apache.

the class ObservationManagerImpl method onEvent.

public void onEvent(EventBundle eventBundle) {
    // get active listeners
    Map<EventListener, EventFilter> activeListeners;
    synchronized (subscriptions) {
        ensureReadOnlyMap();
        activeListeners = readOnlySubscriptions;
    }
    for (Map.Entry<EventListener, EventFilter> entry : activeListeners.entrySet()) {
        EventListener listener = entry.getKey();
        EventFilter filter = entry.getValue();
        FilteredEventIterator eventIter = new FilteredEventIterator(eventBundle.getEvents(), eventBundle.isLocal(), filter, resolver, wspManager.getIdFactory());
        if (eventIter.hasNext()) {
            try {
                listener.onEvent(eventIter);
            } catch (Throwable t) {
                log.warn("EventConsumer threw exception: " + t.toString());
                log.debug("Stacktrace: ", t);
            // move on to the next listener
            }
        }
    }
}

Example 2 with EventFilter

use of org.apache.jackrabbit.spi.EventFilter in project jackrabbit by apache.

the class EventSubscription method setFilters.

/**
     * Sets a new list of event filters for this subscription.
     *
     * @param filters the new filters.
     * @throws RepositoryException if the filters array contains a unknown
     *                             implementation of EventFilters.
     */
void setFilters(EventFilter[] filters) throws RepositoryException {
    // check type
    for (EventFilter filter : filters) {
        if (!(filter instanceof EventFilterImpl)) {
            throw new RepositoryException("Unknown filter implementation");
        }
    }
    List<EventFilter> tmp = new ArrayList<EventFilter>(Arrays.asList(filters));
    this.filters = Collections.unmodifiableList(tmp);
}

Example 3 with EventFilter

use of org.apache.jackrabbit.spi.EventFilter in project jackrabbit by apache.

the class ObservationManagerImpl method addEventListener.

public void addEventListener(EventListener listener, int eventTypes, String absPath, boolean isDeep, String[] uuids, String[] nodeTypeNames, boolean noLocal) throws RepositoryException {
    EventFilter filter = createEventFilter(eventTypes, absPath, isDeep, uuids, nodeTypeNames, noLocal);
    synchronized (subscriptions) {
        subscriptions.put(listener, filter);
        readOnlySubscriptions = null;
    }
    if (subscriptions.size() == 1) {
        wspManager.addEventListener(this);
    } else {
        wspManager.updateEventFilters();
    }
}

Example 4 with EventFilter

use of org.apache.jackrabbit.spi.EventFilter in project jackrabbit by apache.

the class EventSubscription method getEventBundles.

/**
     * @return all the pending event bundles.
     */
EventBundle[] getEventBundles(long timeout) {
    EventBundle[] bundles;
    synchronized (eventBundles) {
        if (eventBundles.isEmpty()) {
            try {
                eventBundles.wait(timeout);
            } catch (InterruptedException e) {
            // continue
            }
        }
        bundles = eventBundles.toArray(new EventBundle[eventBundles.size()]);

            if (eventFilters == null || eventFilters.length == 0) {
                filteredEvents.add(e);
            } else {
