Class CollectorStreamRDF

java.lang.Object

org.apache.jena.riot.lang.CollectorStreamRDF

All Implemented Interfaces:

StreamRDF

public class CollectorStreamRDF
extends Object
implements StreamRDF

StreamRDF implementations which stores received triples and quads in a Collection. The resulting collection can be retrieved via the getTriples() and getQuads() methods. The implementations are suitable for single-threaded parsing, for use with small data or distributed computing frameworks (e.g. Hadoop) where the overhead of creating many threads for a push-pull parser setup is significant.
