      public static org.apache.jena.sparql.algebra.Op transform(org.apache.jena.sparql.algebra.Op op, Predicate<org.apache.jena.graph.Node> testTransform)
      Transform function based on a predicate that accepts a Node to test. A return value of true maps to SUSTITUTE_AND_FILTER and false to RETAIN.
      Parameters:
      op -
      testTransform -
      Returns:

      public static org.apache.jena.sparql.algebra.Op transform(org.apache.jena.sparql.algebra.Op op, BiFunction<org.apache.jena.graph.Node,Integer,SubstitutionStrategy> testTransform)
      Transform function that decides whether to replace a concrete node based on a BiFunction. The BiFunction receives the node and and the index in the triple/quad and must return an appropriate SubstitutionStrategy value. Indexes: 0=s, 1=p, 2=o, 3=g Note that the graph component has index 3 in order to allow for uniform handling of triples and quads.
      Parameters:
      op -
      testTransform -
      Returns:
