Method Details
- iteratorForMatches
  
  ExtendedIterator<Triple> iteratorForMatches(Node index, Node n2, Node n3)
  
  Answer an iterator over all the triples in this map that match the pattern.
  
  Parameters:
  
  index - The node to match as key.
  
  n2 - A node to match, or Node.ANY.
  
  n3 - A node to match, or Node.ANY.
  
  Returns:
  
  An iterator over all the triples in this map that match the pattern.
- streamForMatches
  
  Stream<Triple> streamForMatches(Node index, Node n2, Node n3)
  
  Answer a stream over all the triples in this map that match the pattern.
  
  Parameters:
  
  index - The node to match as key.
  
  n2 - A node to match, or Node.ANY.
  
  n3 - A node to match, or Node.ANY.
  
  Returns:
  
  A stream over all the triples in this map that match the pattern.
- containsMatch
  
  boolean containsMatch(Node index, Node n2, Node n3)
  
  Answer true iff this map contains a triple that matches the pattern.
  
  Parameters:
  
  index - The node to match as key.
  
  n2 - A node to match, or Node.ANY.
  
  n3 - A node to match, or Node.ANY.
  
  Returns:
  
  True iff this map contains a triple that matches the pattern.
- copy
  
  NodeToTriplesMap copy()
  
  Create a copy of this map. The new map will contain all the same nodes as keys of this map, but copies of the bunches as values.
  
  Returns:
  
  an independent copy of this map
