  - beforeConcurrentHandling
```
public <T> void beforeConcurrentHandling(NativeWebRequest request,
                                         Callable<T> task)
                                  throws Exception
```
    This implementation is empty.
    Specified by:
    beforeConcurrentHandling in interface CallableProcessingInterceptor
    Parameters:
    request - the current request
    task - the task for the current async request
    Throws:
    Exception - in case of errors
  - preProcess
```
public <T> void preProcess(NativeWebRequest request,
                           Callable<T> task)
                    throws Exception
```
    This implementation is empty.
    Specified by:
    preProcess in interface CallableProcessingInterceptor
    Parameters:
    request - the current request
    task - the task for the current async request
    Throws:
    Exception - in case of errors
  - postProcess
```
public <T> void postProcess(NativeWebRequest request,
                            Callable<T> task,
                            Object concurrentResult)
                     throws Exception
```
    This implementation is empty.
    Specified by:
    postProcess in interface CallableProcessingInterceptor
    Parameters:
    request - the current request
    task - the task for the current async request
    concurrentResult - the result of concurrent processing, which could be a Throwable if the Callable raised an exception
    Throws:
    Exception - in case of errors
  - handleTimeout
```
public <T> Object handleTimeout(NativeWebRequest request,
                                Callable<T> task)
                         throws Exception
```
    This implementation always returns RESULT_NONE.
    Specified by:
    handleTimeout in interface CallableProcessingInterceptor
    Parameters:
    request - the current request
    task - the task for the current async request
    Returns:
    a concurrent result value; if the value is anything other than CallableProcessingInterceptor.RESULT_NONE or CallableProcessingInterceptor.RESPONSE_HANDLED, concurrent processing is resumed and subsequent interceptors are not invoked
    Throws:
    Exception - in case of errors
  - afterCompletion
```
public <T> void afterCompletion(NativeWebRequest request,
                                Callable<T> task)
                         throws Exception
```
    This implementation is empty.
    Specified by:
    afterCompletion in interface CallableProcessingInterceptor
    Parameters:
    request - the current request
    task - the task for the current async request
    Throws:
    Exception - in case of errors
