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

Method Summary

Modifier and Type	Method and Description
void	monitor(Object service, ServiceID serviceID) Begin monitoring the service
void	register(FaultDetectionListener listener) Register a FaultDetectionListener
void	setConfiguration(String[] configArgs) Set configuration attributes for the FaultDetectionHandler.
void	terminate() Terminate the FaultDetectionHandler

Method Detail

setConfiguration

void setConfiguration(String[] configArgs)

Set configuration attributes for the FaultDetectionHandler.

Parameters:

configArgs - Configuration attributes a FaultDetectionHandler will use to monitor the service. Values are specific to a concrete instance of the FaultDetectionHandler

register

void register(FaultDetectionListener listener)

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

terminate

void terminate()

Terminate the FaultDetectionHandler
