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:

Parameters:

unitOfWork - The UnitOfWork that is processing the message

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

Returns:
