public void writeNIF(List<Document> document,
                     OutputStream os)

Description copied from interface: NIFWriter

Writes the given lost of Document instances as NIF data to the given Writer.

Note that following the recommendations of the Jena framework we highly recommend to use NIFWriter.writeNIF(List, OutputStream) instead of using a Writer since the OutputStream is not relying on a specific encoding.

Specified by:

writeNIF in interface NIFWriter

Parameters:

document - the list of Document instances that should be written as NIF data

writer - the Writer to which the NIF data should be written
