    • declarePredicateSeen

      public void declarePredicateSeen(boolean isFwd, org.apache.jena.graph.Node p)
      Declare a predicate to be seen. This creates an entry for it with an empty set of values. The set of values can be updated later.

    • find

      public Stream<org.apache.jena.graph.Triple> find(boolean isFwd, org.apache.jena.graph.Node p, org.apache.jena.graph.Node o)
      Yield triples matching the predicate and object patterns Returns null if Node.ANY is requested for p but the index is not marked as complete. In other words, this method refuses to yield partial results.
      Parameters:
      isFwd -
      p -
      o -
      Returns:

    • getFromCache

      public Set<org.apache.jena.graph.Node> getFromCache(org.apache.jena.sparql.path.Path path)
      Returns the set of items (possibly empty) if known. A result of null indicates that the cache does not that set.
