All Implemented Interfaces:

ISwitchCall, InvocationHandler

public class ServiceInvocationHandler
extends AbstractServiceInvocationHandler
implements InvocationHandler, ISwitchCall

Service invocation interceptor. It has a multi collection of interceptors per method. Executes the list of interceptors one by one. In case no handler can be found a fallback handler is used.
