Interface FaultDetectionHandler

All Known Implementing Classes:
AbstractFaultDetectionHandler, GigaSpacesFaultDetectionHandler
public interface FaultDetectionHandler
The FaultDetectionHandler is loaded by client entities do determine whether a service is reachable. Developers may choose to implement custom fault detection algorithms and protocols to determine service reachability and use those approaches in concrete implementations of this interface

      Register a FaultDetectionListener
      Parameters:
      listener - The FaultDetectionListener to register

    • monitor

      void monitor(Object service, ServiceID serviceID) throws Exception
      Begin monitoring the service
      Parameters:
      service - The service that the FaultDetectionHandler will monitor, must not be null
      serviceID - An Object representing a unique service identifier for the service being monitored, must not be null
      Throws:
      Exception - If there are abnormal conditions encountered
      NullPointerException - if required parameters are null
