Examples of org.rhq.core.pc.drift.ScheduleQueue

org.rhq.core.pc.drift.ScheduleQueue
Manages the drift detection schedules that are processed by the drift detector. The queue has a concept of the currently "active" schedule. This is identified simply as the schedule returned from {@link #getNextSchedule()} which is the previous head of thequeue. A reference to the active schedule needs to be maintained because at any point in time the server can send a request to update the drift definition that is attached to a schedule. That schedule will either be on the queue waiting to be processed or in the "active" state meaning it is currently being processed by the drift detector.


    @Override
    public List<DriftDefinition> getDeletedDefinitions(int resourceId, Set<DriftDefinition> definitionsFromServer) {
        log.debug("Checking for drift definitions that need to be deleted for resource id " + resourceId);
        List<DriftDefinition> deleted = new LinkedList<DriftDefinition>();
        ScheduleQueue queue = driftMgr.getSchedulesQueue();


        for (DriftDetectionSchedule schedule : getSchedulesForResource(resourceId, queue.toArray())) {
            if (!definitionsFromServer.contains(schedule.getDriftDefinition())) {
                if (log.isDebugEnabled()) {
                    log.debug("Detected stale drift definition that needs to be purged - "
                        + toString(resourceId, schedule.getDriftDefinition()));
                }

    @Override

        ScheduleQueue queue = driftMgr.getSchedulesQueue();
        DriftDefinitionComparator comparator = new DriftDefinitionComparator(
            BOTH_BASE_INFO_AND_DIRECTORY_SPECIFICATIONS);
        List<DriftDefinition> added = new LinkedList<DriftDefinition>();


        for (DriftDefinition c : definitionsFromServer) {
            if (!queue.contains(resourceId, c, comparator)) {
                if (log.isDebugEnabled()) {
                    log.debug("Detected new drift definition that needs to be added to local inventory - "
                        + toString(resourceId, c));
                }
                added.add(c);
