Method Detail

beforeConcurrentHandling

public <T> void beforeConcurrentHandling(NativeWebRequest request,
                                         DeferredResult<T> deferredResult)
                                  throws Exception

This implementation is empty.

Specified by:

beforeConcurrentHandling in interface DeferredResultProcessingInterceptor

Parameters:

request - the current request

deferredResult - the DeferredResult for the current request

Throws:

Exception - in case of errors

preProcess

public <T> void preProcess(NativeWebRequest request,
                           DeferredResult<T> deferredResult)
                    throws Exception

This implementation is empty.

Specified by:

preProcess in interface DeferredResultProcessingInterceptor

Parameters:

request - the current request

deferredResult - the DeferredResult for the current request

Throws:

Exception - in case of errors

postProcess

public <T> void postProcess(NativeWebRequest request,
                            DeferredResult<T> deferredResult,
                            Object concurrentResult)
                     throws Exception

This implementation is empty.

Specified by:

postProcess in interface DeferredResultProcessingInterceptor

Parameters:

request - the current request

deferredResult - the DeferredResult for the current request

concurrentResult - the result to which the DeferredResult

Throws:

Exception - in case of errors

handleTimeout

public <T> boolean handleTimeout(NativeWebRequest request,
                                 DeferredResult<T> deferredResult)
                          throws Exception

This implementation returns true by default allowing other interceptors to be given a chance to handle the timeout.

Specified by:

handleTimeout in interface DeferredResultProcessingInterceptor

Parameters:

request - the current request

deferredResult - the DeferredResult for the current request; if the DeferredResult is set, then concurrent processing is resumed and subsequent interceptors are not invoked

Returns:

true if processing should continue, or false if other interceptors should not be invoked

Throws:

Exception - in case of errors

afterCompletion

public <T> void afterCompletion(NativeWebRequest request,
                                DeferredResult<T> deferredResult)
                         throws Exception

This implementation is empty.

Specified by:

afterCompletion in interface DeferredResultProcessingInterceptor

Parameters:

request - the current request

deferredResult - the DeferredResult for the current request

Throws:

Exception - in case of errors
