use of org.mule.runtime.api.metadata.DataType in project mule by mulesoft.

the class DefaultTransformationService method getPayload.

/**

 * be checked for compatibility.

 * @param encoding the encoding to use if required
 * @return The converted payload of this message. Note that this method will not alter the payload of this message <b>unless</b>
 *         the payload is an {@link InputStream} in which case the stream will be read and the payload will become the fully
 *         read stream.
 * @throws MessageTransformerException if a transformer cannot be found or there is an error during transformation of the payload.
