setDocumentBuilder

public void setDocumentBuilder(javax.xml.parsers.DocumentBuilderFactory documentBuilderFactory)

setXmlPayloadConverter

public void setXmlPayloadConverter(XmlPayloadConverter xmlPayloadConverter)

splitMessage

protected java.lang.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.
