Class StreamingRDFWriter

java.lang.Object

org.deri.tarql.StreamingRDFWriter

public class StreamingRDFWriter
extends java.lang.Object

Writes an iterator over triples to N-Triples or Turtle in a streaming fashion, that is, without needing to hold the entire thing in memory.

Instances are single-use.

There doesn't seem to be a pre-packaged version of this functionality in Jena/ARQ that doesn't require a Graph or Model.
