Lars G. Svensson commented on ANY23-388:
----------------------------------------
No, the problem is not the lower layer API, I just want to be able to access
the instance of RDF4J NTriplesWriter so that I can configure it.
My first suggestion would be to make the field
{{org.apache.any23.writer.RDFWriterTripleHandler.writer}} protected instead of
private. Then I could first create the RDFWriterTripleHandler from the subclass
and after that access the writer and configure it:
{code}
public class SomethingDoer {
// overwrite the NTriplesWriter and add a configuration
private class MyNTriplesWriter extends NTriplesWriter {
public MyNTriplesWriter( OutputStream os ) {
super( os );
final WriterConfig config = new WriterConfig();
config.set(NTriplesWriterSettings.ESCAPE_UNICODE, Boolean.TRUE);
this.writer.setWriterConfig(config);
}
}
public void doSomething() throws Exception {
final DocumentSource source = ...;
final ByteArrayOutputStream os = new ByteArrayOutputStream();
// instantiate the NTriplesHandler with the overwritten one
final TripleHandler handler = new MyNTriplesHandler(os);
try {
runner.extract(source, handler);
} finally {
handler.close();
}
}
}
{code}
Does that seem an acceptable solution to you?

> Project: Apache Any23
> Issue Type: Improvement
> Components: core
> Affects Versions: 2.2
> Reporter: Lars G. Svensson
> Priority: Minor
>
> When using the NTriplesWriter, I wanted to configure it to write unicode
> points as escape sequences. I tried to subclass
> org.apache.any23.writer.TripleHandler and overwrite the access to the
> org.eclipse.rdf4j.rio.ntriples.NTriplesWriter but couldn't do that since the
> access to the NTriplesWriter is package protected. I ended up copying the
> code which seems a bit clunky...
> I was [asked to create a pull

> this issue is there to track that.
