Writing triples directly onto a file, keeping memory empty

[Zak Mc Kracken]

Hi all,

I guess the subject said it all already: I have to convert data to RDF 
and I'd like to write triples on a file as they come in from the 
converter. Is this possible in Jena? I've read about RDF streams 
(https://jena.apache.org/documentation/io/streaming-io.html), but I'm 
not sure it's what I'm looking for (the interfaces expects to start from 
a model).

Thank you in advance,
Marco.
