      A ManagedObject change is being prepared. To cancel preparation set the deny reason to a SNMPv2/v3 error status.
      Parameters:
      changeEvent - the change event object.

    • afterPrepareMOChange

      void afterPrepareMOChange(MOChangeEvent changeEvent)
      A change has been prepared. Setting the deny reason of the supplied event object will be ignored.

      void beforeMOChange(MOChangeEvent changeEvent)
      A ManagedObject change is being committed. To cancel the commit phase set the deny reason to a SNMPv2/v3 error status.

      changeEvent - the change event object.

      void afterMOChange(MOChangeEvent changeEvent)
      A change has been committed. Setting the deny reason of the supplied event object will be ignored.
