public class UnmarshallingTransformer
extends AbstractPayloadTransformer<Object,Object>

An implementation of Transformer that delegates to an OXM Unmarshaller. Expects the payload to be of type Document, String, File, Source or to have an instance of SourceFactory that can convert to a Source. If alwaysUseSourceFactory is set to true, then the SourceFactory will be used to create the Source regardless of payload type.

The alwaysUseSourceFactory is ignored if payload is MimeMessage.

The Unmarshaller may return a Message, but if the return value is not already a Message instance, a new Message will be created with that return value as its payload.
