    • scanForSlaveNodes

      public List<Integer> scanForSlaveNodes()
      Node scanning. Returns a list of slave nodes that respond to a read exception status request (perhaps with an error, but respond nonetheless). Note: a similar scan could be done for registers in nodes, but, for one thing, it would take some time to run, and in any case the results would not be meaningful since there would be no semantic information accompanying the results.
      返回:
      a List object.
