  • Field Details

    • step

      protected org.apache.jena.sparql.path.P_Path0 step

    • alias

      protected String alias

    • targetComponent

      protected org.apache.jena.graph.Node targetComponent
      The component targeted by this step. A step corresponds to a tuple: By default a path points to the values reachable via this step, but in the case of RDF it could also refer to the predicate or graph component.
