  • Method Details

    • name

      default String name()
      Name to identify Nodemanager

    • working

      void working(T node)
      Called when a failed node is working (ready for production) again

    • failed

      void failed(T node)
      Called when a working node fails

    • ping

      void ping(ClusterMonitor<T> clusterMonitor, T node, Executor executor)
      Called when a node should be pinged. This *must* lead to either a call to ClusterMonitor.failed or ClusterMonitor.responded

    • pingIterationCompleted

      default void pingIterationCompleted()
      Called right after a ping has been issued to each node. This default implementation does nothing.
