All Implemented Interfaces:

Converter, ConverterMatcher

Direct Known Subclasses:

EnumMapConverter, TreeMapConverter

public class MapConverter
extends AbstractCollectionConverter

Converts a java.util.Map to XML, specifying an 'entry' element with 'key' and 'value' children.

Note: 'key' and 'value' is not the name of the generated tag. The children are serialized as normal elements and the implementation expects them in the order 'key'/'value'.

Supports java.util.HashMap, java.util.Hashtable and java.util.LinkedHashMap.
