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

Class ResultStreamerFromTuple<D,C>

java.lang.Object

org.aksw.jenax.arq.util.tuple.resultset.ResultStreamerFromTuple<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 ResultStreamerFromTuple<D,C>
extends Object
implements ResultStreamer<D,C,org.apache.jena.atlas.lib.tuple.Tuple<C>>

Implementation backed by a supplier of streams of Tuples. Can convert to domain and component representation (if applicable).
