17 | * <code>ObjectToXml</code> converts any object to XML using Xstream. Xstream uses | |
18 | * some clever tricks so objects that get marshalled to XML do not need to implement | |
19 | * any interfaces including Serializable and you don't even need to specify a default | |
20 | * constructor. If <code>MuleMessage</code> is configured as a source type on this | |
21 | * transformer by calling <code>setAcceptUMOMessage(true)</code> then the MuleMessage | |
22 | * will be serialised. This is useful for transports such as TCP where the message | |
23 | * headers would normally be lost. | |
