  • Method Details

    • getNbSlaves

      int getNbSlaves()
      Get the number of slave nodes started by this MBean.
      Returns:
      the number of slave nodes as an integer value.

    • provisionSlaveNodes

      void provisionSlaveNodes(int nbNodes)
      Start or stop the required number of slaves to reach the specified number. This is equivalent to calling provisionSlaveNodes(nbNodes, null).
      Parameters:
      nbNodes - the number of slave nodes to reach.

    • provisionSlaveNodes

      void provisionSlaveNodes(int nbNodes, boolean interruptIfRunning)
      Start or stop the required number of slaves to reach the specified number. This is equivalent to calling provisionSlaveNodes(nbNodes, null).
      Parameters:
      nbNodes - the number of slave nodes to reach.
      interruptIfRunning - if true then nodes can only be stopped once they are idle.

    • provisionSlaveNodes

      void provisionSlaveNodes(int nbNodes, TypedProperties configOverrides)
      Start or stop the required number of slaves to reach the specified number, using the specified config overrides.

      If configOverrides is null, then previous overrides are applied, and already running slave nodes do not need to be stopped.

      Parameters:
      nbNodes - the number of slave nodes to reach.
      configOverrides - the configuration overrides to apply.

    • provisionSlaveNodes

      void provisionSlaveNodes(int nbNodes, boolean interruptIfRunning, TypedProperties configOverrides)
      Start or stop the required number of slaves to reach the specified number, using the specified config overrides.

      If configOverrides is null, then previous overrides are applied, and already running slave nodes do not need to be stopped.

      Parameters:
      nbNodes - the number of slave nodes to reach.
      interruptIfRunning - if true then nodes can only be stopped once they are idle.
      configOverrides - the configuration overrides to apply.
