Interface AStarListener<ST extends GraphSegment<ST,​PT>,​PT extends GraphPoint<PT,​ST>>

  • Type Parameters:
    PT - is the type of node in the graph
    ST - is the type of edge in the graph
    All Superinterfaces:
    EventListener
    public interface AStarListener<ST extends GraphSegment<ST,​PT>,​PT extends GraphPoint<PT,​ST>>
extends EventListener

                              PT endPoint)
        Invoked when the A* algorithm has started.
        Parameters:
        startPoint - is the starting node.
        endPoint - is the target node.

      • nodeConsumed

        default void nodeConsumed​(AStarNode<ST,​PT> node,
                          List<AStarNode<ST,​PT>> openList)
        Invoked when a node is removed from the open list.
        Parameters:
        node - is the node just removed from the open list.
        openList - is the current state of the open list.

      • nodeOpened

        default void nodeOpened​(AStarNode<ST,​PT> node,
                        List<AStarNode<ST,​PT>> openList)
        Invoked when a node is put in the open list.
        Parameters:
        node - is the node just added into the open list.
        openList - is the current state of the open list.

      • nodeReopened

                        List<AStarNode<ST,​PT>> closeList)
        Invoked when a node is put in the close list.
        Parameters:
        node - is the node just added into the close list.
        closeList - is the current state of the close list.

      • algorithmEnded

        default void algorithmEnded​(List<AStarNode<ST,​PT>> closeList)
        Invoked when the A* algorithm has finished.
