Method Detail

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)
