WriterStreamRDFBase (Apache Jena ARQ)

java.lang.Object
- org.apache.jena.riot.writer.WriterStreamRDFBase

All Implemented Interfaces:

StreamRDF

Direct Known Subclasses:

WriterStreamRDFBlocks, WriterStreamRDFFlat
```
public abstract class WriterStreamRDFBase
extends java.lang.Object
implements StreamRDF
```
Core engine for output of triples / quads that is streaming. Handles prefixes and base, together with the environment for processing. If fed quads, the output is valid TriG. If fed only triples, the output is valid Turtle. Not for N-Quads and N-triples.
