Method Details
- makeAbortable
  
  public static <T> Iterator<T> makeAbortable(Iterator<T> iter, List<Abortable> killList)
  
  Create an abortable iterator, storing it in the killList. Just return the input iterator if killList is null.
- tripleHasNodeTriple
  
  public static boolean tripleHasNodeTriple(Triple triple)
  
  Test whether a triple has an triple term as one of its components.
- quadHasNodeTriple
  
  public static boolean quadHasNodeTriple(Quad quad)
  
  Test whether a quad has an triple term as one of its components.
- tripleHasEmbTripleWithVars
  
  public static boolean tripleHasEmbTripleWithVars(Triple triple)
  
  Test whether a triple has a triple term (RDF-star) as one of its components and that embedded triple term has variables.
- quadHasEmbTripleWithVars
  
  public static boolean quadHasEmbTripleWithVars(Quad quad)
  
  Test whether a quad has a triple term (RDF-star) as one of its components and that embedded triple term has variables.
- sameTermAs
  
  public static boolean sameTermAs(Node node1, Node node2)
  
  Test equality of two concrete teams.
- nodeTopLevel
  
  public static Node nodeTopLevel(Node node)
  
  Convert a pattern node into ANY, or leave as a constant term. Any Embedded triple term with a variable, that is {@literal <<?var>>} becomes an ANY.
