use of org.opennms.web.outage.OutageQueryParms in project opennms by OpenNMS.

the class OutageFilterController method handleRequestInternal.

     * (for example, what to filter on or sort by), then does the database query
     * (through the OutageFactory) and then forwards the results to a JSP for
     * display.
