use of net.geoprism.dhis2.dhis2adapter.response.DHIS2Response in project geoprism-registry by terraframe.

the class DHIS2SynchronizationManager method exportGeoObject.

/**
 * It's important that we try our best to maintain an accurate state between
 * our database and the DHIS2 database. The DHIS2Serailizer will create new
 * ids and save them as externalIds for GeoObjects that do not have
 * externalIds. If our push to DHIS2 for this new GeoObject fails for whatever
 * reason, then we want to rollback our database so that we do not store the
 * id which does not exist in the DHIS2 database.
 *
 * TODO : In the future perhaps we should directly ask DHIS2 if an object
 * exists and then we'll know
 *
 * @param level
 * @param go
 * @return
 * @throws ExportError
