    • createNamedGraphStreamFromArgs

      public static io.reactivex.rxjava3.core.Flowable<org.apache.jena.query.Dataset> createNamedGraphStreamFromArgs(List<String> rawArgs, String fmtHint, org.apache.jena.shared.PrefixMapping pm, Collection<org.apache.jena.riot.Lang> quadLangs)
      Default procedure to obtain a stream of named graphs from a list of non-option arguments If the list is empty or the first argument is '-' data will be read from stdin
