Class OtpNodeStatus

  • public class OtpNodeStatus
extends java.lang.Object

    Provides a callback mechanism for receiving status change information about other nodes in the system. Register an instance of this class (or a subclass) with your OtpNode when you wish to be notified about such status changes and other similar events.

    This class provides default handers that ignore all events. Applications are expected to extend this class in order to act on events that are deemed interesting.

    Note that this class is likely to change in the near future
