Actually there's a third option by injecting a modified ConverterLookup:
new NamedMapConverter(xstream.getMapper(), "desk", "name", String.class,
null, HashSet.class, true, false, new ConverterLookup() {
@Override
Converter lookupConverterForClass(Class type) {
if (type == HashSet.class) {
return new NamedCollectionConverter( ... );
} else
return xstream.getConverterLookup().lookupConverterForClass(type);
}
});
You get the idea ...
Cheers,
