Hi
Actually i am using the custom converter.
so i am doing something like
public void marshal(Object source, HierarchicalStreamWriter writer,
MarshallingContext context) {
MCS mcs = (MCS) source;
//couple of the other customization here
if(mcs.getDesks()!=null)
context.convertAnother(mcs.getDesks(),new DeskCollectionConverter());
}
Now i want my DeskCollectionConverter to extend NamedCollectionConverter.
The
NamedCollectionConverter constructor parameters are
NamedCollectionConverter(Class type, Mapper mapper, String itemName, Class
itemType)
How to pass these parameters ?
I am learning and soon will be perfect with XStream.
Regards
Raj
