  • All Implemented Interfaces:
    
public interface DependencyGraph<T>

    This interface allows to separate the usage of a dependency graph from its implementation.

      Modifier and Type Method Description
      abstract void addNeighbor(Node<T> n1, Node<T> n2) Given two nodes, the graph assumes they are now neighbors and calculates the neighborhood dependencies between them.
      abstract void createDependencies(Actionable<T> reactionHandler) This method creates the dependencies when a new reaction is added to the environment.
      abstract void removeDependencies(Actionable<T> reactionHandler) This method removes all the dependencies (both in and out dependencies) for a given reaction handler.
      abstract void removeNeighbor(Node<T> n1, Node<T> n2) Given two nodes, the engine assumes they are no longer neighbors and deletes the neighborhood dependencies between them.
      abstract ListSet<Actionable<T>> outboundDependencies(Actionable<T> reaction) Returns the set of reactions that may be influenced by the provided reaction.

      • addNeighbor

         abstract void addNeighbor(Node<T> n1, Node<T> n2)

        Given two nodes, the graph assumes they are now neighbors and calculates the neighborhood dependencies between them.

        Parameters:
        n1 - The first node
        n2 - The second node

      • createDependencies

         abstract void createDependencies(Actionable<T> reactionHandler)

        This method creates the dependencies when a new reaction is added to the environment. Please be careful when building the environment and populating the existing reactions map: this method assumes that all the dependencies among the existing reactions are correct and up to date.

        Parameters:
        reactionHandler - the reaction handler whose dependencies should be calculated.

      • removeDependencies

         abstract void removeDependencies(Actionable<T> reactionHandler)

        This method removes all the dependencies (both in and out dependencies) for a given reaction handler. This method is meant to be used in order to keep the dependencies clean when removing a reaction.

        Parameters:
        reactionHandler - the reaction handler whose dependencies will be deleted.

      • removeNeighbor

         abstract void removeNeighbor(Node<T> n1, Node<T> n2)

        Given two nodes, the engine assumes they are no longer neighbors and deletes the neighborhood dependencies between them.

        Parameters:
        n1 - The first node
        n2 - The second node

      • outboundDependencies

         abstract ListSet<Actionable<T>> outboundDependencies(Actionable<T> reaction)

        Returns the set of reactions that may be influenced by the provided reaction.

        Parameters:
        reaction - the input reaction
        Returns:

        the set of reactions that may be influenced by the provided reaction
