Package org.aksw.jenax.arq.util.tuple.resultset

Class ResultStreamerFromDomain<D,C>

java.lang.Object

org.aksw.jenax.arq.util.tuple.resultset.ResultStreamerFromDomain<D,C>

Type Parameters:

D - The domain type such as Quad

C - The component type such as Node

All Implemented Interfaces:

ResultStreamer<D,C,org.apache.jena.atlas.lib.tuple.Tuple<C>>

public class ResultStreamerFromDomain<D,C>
extends Object
implements ResultStreamer<D,C,org.apache.jena.atlas.lib.tuple.Tuple<C>>

Implementation backed by a supplier of streams of domain objects such as Quads. Can convert to tuple and component representation (if applicable). Domain objects can only be converted to component representation if they are logical 1-tuples.
