    • Method Detail

      • 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

        @Deprecated
default void ping​(T node,
                  java.util.concurrent.Executor executor)
        Deprecated.
        Use ping(ClusterMonitor clusterMonitor, T node, Executor executor) instead.
        Called when a node should be pinged. This *must* lead to either a call to NodeMonitor.failed or NodeMonitor.responded

      • ping

        default void ping​(ClusterMonitor<T> clusterMonitor,
                  T node,
                  java.util.concurrent.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.
