LifecycleMethodInterceptorsInvocation An {@link Invocation} which is aware of the bean context.The {@link LifecycleMethodInterceptorsInvocation} is used forcreating an AOP invocation for lifecycle callback methods defined either on the bean class or on the interceptor classes associated with the bean. The end target of the {@link LifecycleMethodInterceptorsInvocation}, is always a bean instance. But the target (bean instance) is *never* invoked at the end of the interceptor chain. This is because the lifecycle method(s) may or may not be present on the bean class. If there are any lifecycle methods present on the bean class, then its the responsibility of the code using this {@link LifecycleMethodInterceptorsInvocation} to createan appropriate AOP interceptor (ex: {@link LifecycleCallbackBeanMethodInterceptor}and making it available in the interceptor chain that is passed to the constructor of this class @see LifecycleCallbackBeanMethodInterceptor @see LifecycleCallbackInterceptorMethodInterceptor @author Jaikiran Pai @version $Revision: $
