All Implemented Interfaces:: StreamRDF

Direct Known Subclasses:: WriterStreamRDFBlocks, WriterStreamRDFFlat

public abstract class WriterStreamRDFBase extends Object implements StreamRDF

Core engine for output of triples / quads that is streaming. It covers Turtle and TriG "flat" and "blocks" variants.

It handles prefixes and base and node formats which is controlled by a NodeFormatterTTL.

The output is valid TriG.
If fed only triples, the output is valid Turtle.

For N-Quads and N-triples use WriterStreamRDFPlain.
