Description copied from interface: MessageDispatchInterceptor

Intercepts a given message on dispatching.

The implementer of this method might want to intercept the message before passing it to the chain (effectively before calling MessageDispatchInterceptorChain.proceed(Message, ProcessingContext)) or after the chain (by mapping the resulting message by calling MessageStream.mapMessage(Function)).

Specified by:

interceptOnDispatch in interface MessageDispatchInterceptor<T extends Message>

Parameters:

message - The message to intercept on dispatching.

context - The active processing context, if any. Can be used to (e.g.) validate correlation data.

interceptorChain - The interceptor chain to signal that processing is finished and further interceptors should be called.

Returns:

The resulting message stream from MessageDispatchInterceptorChain.proceed(Message, ProcessingContext).
