  • Method Details

    • getNeighborsIterator

      NodesIterator getNeighborsIterator(int node)
      Iterator over the neighbors of a given node. Only the most recently instantiated iterator is guaranteed to be valid.

    • size

      int size()
      Returns:
      the number of nodes in the graph

    • entryNode

      int entryNode()
      Returns:
      the node of the graph to start searches at

    • getVector

      T getVector(int node)
      Retrieve the vector associated with a given node.

      This will only be called when a search is performed using approximate similarities. In that situation, we will want to reorder the results by the exact similarity at the end of the search.

    • liveNodes

      Bits liveNodes()
      Return a Bits instance indicating which nodes are live. The result is undefined for ordinals that do not correspond to nodes in the graph.

    • getIdUpperBound

      default int getIdUpperBound()
      Returns:
      the largest ordinal id in the graph. May be different from size() if nodes have been deleted.
