Class TreeMapConverter
java.lang.Object
com.thoughtworks.xstream.converters.collections.AbstractCollectionConverter
com.thoughtworks.xstream.converters.collections.MapConverter
com.thoughtworks.xstream.converters.collections.TreeMapConverter
- All Implemented Interfaces:
- Converter, ConverterMatcher
public class TreeMapConverter
- extends MapConverter
Converts a java.util.TreeMap to XML, and serializes
the associated java.util.Comparator. The converter
assumes that the entries in the XML are already sorted
according the comparator.
