      void nodeAdded​(Node n)
      This method is invoked when a new node has joined the platform.
      void nodeReachable​(Node n)
      This method is invoked when the local node discovers that a platform node, that was previously unreachable, has become reachable again.
      void nodeRemoved​(Node n)
      This method is invoked when a node has left the platform.
      void nodeUnreachable​(Node n)
      This method is invoked when the local node discovers that a platform node is not reachable anymore.

    • Method Detail

      • nodeAdded

        void nodeAdded​(Node n)
        This method is invoked when a new node has joined the platform.
        Parameters:
        n - The newly added platform node.

      • nodeRemoved

        void nodeRemoved​(Node n)
        This method is invoked when a node has left the platform.
        Parameters:
        n - The node that has just left.

      • nodeUnreachable

        void nodeUnreachable​(Node n)
        This method is invoked when the local node discovers that a platform node is not reachable anymore. The discovery is due to some IMTP-specific network mechanism, and does not mean that the remote node has failed. A subsequent nodeReachable() call might be issued when the IMTP connection becomes working again.
        Parameters:
        n - The node that has become unreachable.

      • nodeReachable

        void nodeReachable​(Node n)
        This method is invoked when the local node discovers that a platform node, that was previously unreachable, has become reachable again.
        Parameters:
        n - The node that has become reachable again.
