      public void insertNode(Edge edge, String nodeName)
      Convenience method for insertNode(Edge, Node)
      Parameters:
      edge - the edge to split and insert a node into
      nodeName - the name of the node to insert along the edge

    • insertNode

      public void insertNode(Edge edge, Node node)
      Insert an arbitrary node on an existing edge.
      Parameters:
      edge - the edge to split and insert a node into
      node - the node to insert along the edge

    • findEdges

      public Set<Edge> findEdges(Node node)
      Find all edges that are connected to the specific node, both as an outgoing Edge.getFrom() or incoming Edge.getTo() end point.
      Parameters:
      node - the node with potential end points
      Returns:
      the set of edges connected to the node

    • findEdgesFrom

      public Set<Edge> findEdgesFrom(Node from)
      Find all edges that are connected Edge.getFrom() the specific node.
      Parameters:
      from - the node with potential edges from it
      Returns:
      the set of edges from the node

    • getPath

      public Route getPath(String nodeNameOrigin, String nodeNameDest)
      Convenience method for getPath(Node, Node)
      Parameters:
      nodeNameOrigin - the name of the node to the path origin.
      nodeNameDest - the name of the node to the path destination.
      Returns:
      the path to take

    • getPath

      public Route getPath(Node from, Node to)
      Using BFS (Breadth First Search) return the path from a any arbitrary node to any other.
      Parameters:
      from - the node from
      to - the node to
      Returns:
      the path to take or null if there is no path.
