use of io.spine.server.event.EventStreamQuery in project core-java by SpineEventEngine.

the class ProjectionRepository method catchUp.

     * Updates projections from the event stream obtained from {@code EventStore}.
     */

        @Override
        public void run() {
            // Get the timestamp of the last event. This also ensures we have the storage.
            final Timestamp timestamp = nullToDefault(projectionStorage().readLastHandledEventTime());
            final EventStreamQuery query = EventStreamQuery.newBuilder().setAfter(timestamp).addAllFilter(eventFilters).build();
