Class TripleTableFromQuadTable

java.lang.Object
org.aksw.jena_sparql_api.rx.TripleTableFromQuadTable
All Implemented Interfaces:
org.apache.jena.sparql.core.mem.TransactionalComponent, org.apache.jena.sparql.core.mem.TripleTable, org.apache.jena.sparql.core.mem.TupleTable<org.apache.jena.graph.Triple>
public class TripleTableFromQuadTable extends Object implements org.apache.jena.sparql.core.mem.TripleTable
A TripleTable view on top of a QuadTable. Used to create a simple insert-order-preserving Dataset view with proper prefix-mapping support using QuadTable quadTable = new QuadTableFromNestedMaps(); new DatasetGraphInMemory(quadTable, new TripleTableFromQuadTable(quadTable));
