WeakHashMapConverter

java.lang.Object
- com.thoughtworks.xstream.converters.collections.WeakHashMapConverter

All Implemented Interfaces:

Converter, ConverterMatcher
```
public class WeakHashMapConverter
extends java.lang.Object
implements Converter
```
Converts a WeakHashMap. A WeakHashMap is supposed to release its elements when they are no longer referenced. Therefore is at unmarshalling time no guarantee that an entry is still available when it is referenced later in the stream. As consequence the converter will marshal no elements at all, it will create an empty WeakHashMap at unmarshalling time.
