SerializingProvider

@Service(value=SerializingProvider.class)
public class RdfJsonSerializingProvider
extends Object
implements SerializingProvider

A SerializingProvider for rdf/json. This implementation is based on first sorting the triples within the parsed TripleCollection based on the subject.

The serialization is done on a subject scope. Meaning that all triples for a subject are serialized and instantly written to the provided OutputStream.

'UFT-8' is used as encoding to write the data.
