Class RecoveryInterceptor

java.lang.Object

jadex.bridge.service.component.interceptors.AbstractApplicableInterceptor

jadex.bridge.service.component.interceptors.RecoveryInterceptor

All Implemented Interfaces:

IServiceInvocationInterceptor

public class RecoveryInterceptor
extends AbstractApplicableInterceptor

The recovery interceptor is used in required service proxies for automatically reassigning a service if it fails due to one of specific exceptions. todo: - fix that the failed service is not found again by search - which exception should be supported (ComponentTerminatedException, ServiceInvalidException, ServiceNotFoundException?) - what about multi services, if this case there is no abstraction for all services so that only single rebinds can be done (not a new set of services)
