Converter implementations are responsible marshalling Java objects to/from textual data.
If an exception occurs during processing, a ConversionException
should be thrown.
If working with the high level XStream
facade,
you can register new converters using the XStream.registerConverter() method.
If working with the lower level API, the
ConverterLookup
implementation is
responsible for looking up the appropriate converter.
AbstractBasicConverter
provides a starting point for objects that can store all information
in a single String.
AbstractCollectionConverter
provides a starting point for objects that hold a collection of other objects
(such as Lists and Maps).
