Examples of org.switchyard.transform.Transformer

org.switchyard.transform.Transformer
Handles transformation between message content types (e.g. Object -> XML) to reconcile the type systems used by a service consumer and provider. A Transformer instance can be directly attached to an exchange or it can be registered in the TransformerRegistry and loaded dynamically based on the from and to message names. @param < F> Java type representing the from, or source, format @param < T> Java type representing the to, or target, format

        XMLUnit.compareXML(PO_XML, resultXML);
    }
