Example 1 with CircularFifoQueue

use of org.apache.commons.collections4.queue.CircularFifoQueue in project xwiki-platform by xwiki.

the class XWikiStatsServiceImpl method onEvent.

@Override
public void onEvent(Event event, Object source, Object data) {
    if (Utils.getComponent(RemoteObservationManagerContext.class).isRemoteState()) {
        // take care of this
        return;

    ActionExecutedEvent actionEvent = (ActionExecutedEvent) event;
    XWikiDocument document = (XWikiDocument) source;
    XWikiContext context = (XWikiContext) data;
    // anything in the database)
    if (context.getWiki().isReadOnly()) {
        return;
    }
    // Initialize cookie used as unique identifier of a user visit and put it in the context
    StatsUtil.findCookie(context);
    String action = actionEvent.getActionName();
    // Let's save in the session the last elements view, saved
    synchronized (this) {
        if (!action.equals(DownloadAction.ACTION_NAME)) {
            Collection actions = StatsUtil.getRecentActionFromSessions(context, action);
