Description copied from class: IntegrationObjectSupport

splitMessage

protected final Object splitMessage(Message<?> message)
Description copied from class: 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.
