In most cases the provided converters should suffice, however, in certain cases you may want to create your own converters. To do so create a class that implements com.thoughtworks.xstream.converters.Converter and implement the void marshal(Object source, HierarchicalStreamWriter writer, MarshallingContext context); and Object unmarshal(HierarchicalStreamReader reader, UnmarshallingContext context); The example below demonstrates a CustomConverter. To make the example more interesting we will write a converter to serialize a BufferedImage. The image for the example can be
