Class DecouplingInterceptor

java.lang.Object

jadex.bridge.service.component.interceptors.AbstractMultiInterceptor

jadex.bridge.service.component.interceptors.DecouplingInterceptor

All Implemented Interfaces:

IServiceInvocationInterceptor

public class DecouplingInterceptor
extends AbstractMultiInterceptor

Invocation interceptor for executing a call on the underlying component thread. It checks whether the call can be decoupled (has void or IFuture return type) and the invoking thread is not already the component thread. todo: what about synchronous calls that change the object state. These calls could damage the service state.
