  • Constructor Details

    • Vertex

      Vertex(S2Point location)
      Build a non-processed vertex not owned by any node yet.
      Parameters:
      location - vertex location

  • Method Details

    • getLocation

      public S2Point getLocation()
      Get Vertex location.
      Returns:
      vertex location

    • bindWith

      void bindWith(Circle circle)
      Bind a circle considered to contain this vertex.
      Parameters:
      circle - circle to bind with this vertex

    • sharedCircleWith

      Circle sharedCircleWith(Vertex vertex)
      Get the common circle bound with both the instance and another vertex, if any.

      When two vertices are both bound to the same circle, this means they are already handled by node associated with this circle, so there is no need to create a cut hyperplane for them.

      Parameters:
      vertex - other vertex to check instance against
      Returns:
      circle bound with both the instance and another vertex, or null if the two vertices do not share a circle yet

    • setIncoming

      void setIncoming(Edge incoming)
      Set incoming edge.

      The circle supporting the incoming edge is automatically bound with the instance.

      Parameters:
      incoming - incoming edge

    • getIncoming

      public Edge getIncoming()
      Get incoming edge.
      Returns:
      incoming edge

    • setOutgoing

      void setOutgoing(Edge outgoing)
      Set outgoing edge.

      The circle supporting the outgoing edge is automatically bound with the instance.

      Parameters:
      outgoing - outgoing edge

    • getOutgoing

      public Edge getOutgoing()
      Get outgoing edge.
      Returns:
      outgoing edge
