Method Detail

handle

public Object handle(@Nonnull
                     UnitOfWork<? extends T> unitOfWork,
                     @Nonnull
                     InterceptorChain interceptorChain)
              throws Exception

Deprecated.

Description copied from interface: MessageHandlerInterceptor

Invoked before a Message is handled by a designated MessageHandler.

The interceptor is responsible for the continuation of the handling process by invoking the InterceptorChain.proceed() method on the given interceptorChain.

The given unitOfWork contains contextual information. Any information gathered by interceptors may be attached to the unitOfWork.

Interceptors are highly recommended not to change the type of the message handling result, as the dispatching component might expect a result of a specific type.

Specified by:

handle in interface MessageHandlerInterceptor<T extends Message<?>>

Parameters:

unitOfWork - The UnitOfWork that is processing the message

interceptorChain - The interceptor chain that allows this interceptor to proceed the dispatch process

Returns:

the result of the message handler. May have been modified by interceptors.

Throws:

Exception - any exception that occurs while handling the message

handle

@Nonnull
public BiFunction<Integer,T,T> handle(@Nonnull
                                               List<? extends T> messages)

Deprecated.

Description copied from interface: MessageDispatchInterceptor

Apply this interceptor to the given list of messages. This method returns a function that can be invoked to obtain a modified version of messages at each position in the list.

Specified by:

handle in interface MessageDispatchInterceptor<T extends Message<?>>

Parameters:

messages - The Messages to pre-process

Returns:

a function that processes messages based on their position in the list

validateMessage

protected Set<javax.validation.ConstraintViolation<Object>> validateMessage(Object message,
                                                                            javax.validation.Validator validator)

Deprecated.

Validate the given message using the given validator. The default implementation merely calls validator.validate(message).

Subclasses may override this method to alter the validation behavior in specific cases. Although the null is accepted as return value to indicate that there are no constraint violations, implementations are encouraged to return an empty Set instead.

Parameters:

message - the message to validate

validator - the validator provided by the validator factory

Returns:

a set of ConstraintViolations. May also return null
