Clearly I meant 1024 for 1 kiB (but anyway, once this works, I would
like to set it to 100k)
I was thinking that perhaps marks are being overridden, otherwise
XML-based parsers would fail as they could not encounter the closing tag
(e.g. </rdf:RDF>).
So I was thinking, perhaps I should override the SimpleMGraph and set a
limit to the triples instead?
Thank You

Hi,
I need to write a function that performs lookahead of the OWL ontology
ID for a Graph, therefore it has to scan the content up to a certain
point to see if it has found an ontology IRI / version IRI pair.
I thought that setting mark() on a BufferedInputStream did the trick,
something like:
MGraph graph = new SimpleMGraph();
BufferedInputStream bIn = new BufferedInputStream(content);
bIn.mark(1240); // Read up to 1k
parser.parse(graph, bIn, SupportedFormat.RDF_XML);
(parser has a Jena parser provider registered)
But apparently this is not working. Even for streams much longer than
1 kiB, with the interesting triples right at the very end, these
triples are always found.
Do the Clerezza parser override the marks on a buffered stream, or
maybe Jena is doing so? Or even better, am I doing this wrong?
Best,
