Class TriGWriter

java.lang.Object
  de.fuberlin.wiwiss.ng4j.trig.TriGWriter

All Implemented Interfaces:

NamedGraphSetWriter

public class TriGWriter
extends Object
implements NamedGraphSetWriter

Serializes a NamedGraphSet as a TriG file (see TriG specification).

This class is typically not used directly, but through the NamedGraphSet.write methods.

When used directly, custom namespace prefixes can be defined:

TriGWriter writer = new TriGWriter();
 writer.addNamespace("ex", "http://example.org/");
 writer.write(myNamedGraphSet, System.out, "http://example.org/baseURI");
