/**
* Converter implementations are responsible marshalling Java objects
* to/from textual data.
*
* If an exception occurs during processing, a {@link ConversionException}
* should be thrown.
*
* If working with the high level {@link com.thoughtworks.xstream.XStream} facade,
* you can register new converters using the XStream.registerConverter() method.
*
* If working with the lower level API, the
* {@link com.thoughtworks.xstream.converters.ConverterLookup} implementation is
* responsible for looking up the appropriate converter.
*
* Converters for object that can store all information in a single value
* should implement {@link com.thoughtworks.xstream.converters.SingleValueConverter}.
*
{@link com.thoughtworks.xstream.converters.basic.AbstractSingleValueConverter}
* provides a starting point.
*
* {@link com.thoughtworks.xstream.converters.collections.AbstractCollectionConverter}
* provides a starting point for objects that hold a collection of other objects
* (such as Lists and Maps).
