Examples of org.geoserver.wfs.TransactionEvent

org.geoserver.wfs.TransactionEvent
Event carrying information about a change that happened/that is about to occur. The feature collection may be an in-memory one, or may be based on a real data store with a filter.

        List entries = new ArrayList();
