AbstractMessageSplitter
- Subclasses must override this method to split the received Message. The
return value may be a Collection or Array. The individual elements may
be Messages, but it is not necessary. If the elements are not Messages,
each will be provided as the payload of a Message. It is also acceptable
to return a single Object or Message. In that case, a single reply
Message will be produced.
