Example 1 with EventsQueryResult

use of org.bedework.calcore.hibernate.EventQueryBuilder.EventsQueryResult in project bw-calendar-engine by Bedework.

the class CoreEvents method getEvent.

     *
     * First try to retrieve the master event from the events table.
     *
     * If not there try the annotations table. If it's there, it's a reference
     * to an event owned by somebody else. Otherwise we drew a blank.
     *
     * If no recurrence id was specified process any recurrence information for
     * each event retrieved and return.
     *
     * Note that the event we retrieved might be a reference to a recurring
     * instance. In that case it will inherit the recurrence id. We should check
     * for this case and assume we were being asked for that event.
     *
     * If a recurrence id was specified then, for each master event retrieved,
     * we need to retrieve the instance and build a proxy using any appropriate
     * overrides.
