org.springframework.web.method.support.ModelAndViewContainer
Records model and view related decisions made by {@link HandlerMethodArgumentResolver}s and {@link HandlerMethodReturnValueHandler}s during the course of invocation of a controller method.
The {@link #setRequestHandled} flag can be used to indicate the requesthas been handled directly and view resolution is not required.
A default {@link Model} is automatically created at instantiation.An alternate model instance may be provided via {@link #setRedirectModel}for use in a redirect scenario. When {@link #setRedirectModelScenario} is setto {@code true} signalling a redirect scenario, the {@link #getModel()}returns the redirect model instead of the default model. @author Rossen Stoyanchev @since 3.1
