Package jadex.bridge.service.component.interceptors

Class ResolveInterceptor

  • All Implemented Interfaces:
    IServiceInvocationInterceptor
    public class ResolveInterceptor
extends AbstractApplicableInterceptor
    The resolve interceptor is responsible for determining the object on which the method invocation is finally performed. Checks whether the object is a ServiceInfo. In this case it delegates method calls of I(Internal)Service to the automatically created BasicService instance and all other calls to the domain object. // todo: much annotation stuff and injection of objects to the pojo.
