List of GetDatastream() Examples

Examples of GetDatastream()

org.fcrepo.server.storage.DOReader.GetDatastream()
Gets a particular Datastream in the digital object. If the date given is null, the most recent version of the datastream is given. If the date is non-null, the closest version of the Datastream to the specified date/time (without going over) is given. If no datastreams match the given criteria, null is returned. @param datastreamID The Datastream identifier @param versDateTime The date-time stamp to get appropriate Datastream version @return a particular Datastream in the digital object. @throws ServerException If any type of error occurred fulfilling the request.
