Examples with DeviceEventListResult org.eclipse.kapua.service.device.registry.event.DeviceEventListResult used on opensource projects

Example 1 with DeviceEventListResult

use of org.eclipse.kapua.service.device.registry.event.DeviceEventListResult in project kapua by eclipse.

the class DeviceEventServiceImpl method query.

@Override
public DeviceEventListResult query(KapuaQuery<DeviceEvent> query) throws KapuaException {
    // 
    // Argument Validation
    ArgumentValidator.notNull(query, "query");
    ArgumentValidator.notNull(query.getScopeId(), "query.scopeId");
    // 
    // Check Access
    authorizationService.checkPermission(permissionFactory.newPermission(DeviceEventDomain.DEVICE_EVENT, Actions.read, query.getScopeId()));
    // 
    // Do Query
    DeviceEventListResult result = null;
    EntityManager em = DeviceEntityManagerFactory.getEntityManager();
    try {
        result = DeviceEventDAO.query(em, query);
    } catch (Exception e) {
        throw KapuaExceptionUtils.convertPersistenceException(e);
    } finally {
        em.close();
    }
    return result;
}

Example 2 with DeviceEventListResult

use of org.eclipse.kapua.service.device.registry.event.DeviceEventListResult in project kapua by eclipse.

the class Devices method getEvents.

/**
 * Returns the events for the device identified by the specified
 * ClientID under the account of the currently connected user.
 * <p>
 * If the flag DeviceEventsResult.limitExceeded is set, the maximum number
 * of entries to be returned has been reached, more events exist and can
 * be read by moving the offset forward in a new request
 *
 * @param deviceId
 *            The client ID of the device requested.
 * @param limit
 *            Maximum number of entries to be returned.
 * @param offset
 *            Starting offset for the entries to be returned.
 * @param startDate
 *            Start date of the date range requested. The parameter
 *            is expressed as a long counting the number of milliseconds since
 *            January 1, 1970, 00:00:00 GMT. The default value of 0 means no
 *            start date. Alternatively, the date can be expressed as a string
 *            following the ISO 8601 format.
 * @param endDate
 *            End date of the date range requested. The parameter
 *            is expressed as a long counting the number of milliseconds since
 *            January 1, 1970, 00:00:00 GMT. The default value of 0 means no
 *            start date. Alternatively, the date can be expressed as a string
 *            following the ISO 8601 format.
 * @return The list of Events
