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.
