Examples of pignlproc.storage.UriStringLiteralNTriplesLoader$IStream

org.eclipse.jetty.http2.IStream
Pig loader for NTriples formatted RDF files assuming that subject, predicate are valid URIs (e.g. clear of any whitespace character) and that the object is Literal. Returns the subject and the object (parsed as a String) and the language code if any (or null). The property value can be given as a filter. The NTriples literal parsing is taken from the Jena project (which unfortunately does not offer a pure String API that does not allocate Jena specific java objects.
