ServletInvocableHandlerMethod (Spring Framework 4.3.30.RELEASE API)

java.lang.Object
- org.springframework.web.method.HandlerMethod
- - org.springframework.web.method.support.InvocableHandlerMethod
  - - org.springframework.web.servlet.mvc.method.annotation.ServletInvocableHandlerMethod

```
public class ServletInvocableHandlerMethod
extends InvocableHandlerMethod
```
Extends InvocableHandlerMethod with the ability to handle return values through a registered HandlerMethodReturnValueHandler and also supports setting the response status based on a method-level @ResponseStatus annotation.
A null return value (including void) may be interpreted as the end of request processing in combination with a @ResponseStatus annotation, a not-modified check condition (see ServletWebRequest.checkNotModified(long)), or a method argument that provides access to the response stream.
