                                 MarshallingContext context)

unmarshal

public Object unmarshal(HierarchicalStreamReader reader,
                        UnmarshallingContext context)

Description copied from interface: Converter

Convert textual data back into an object.

Specified by:

unmarshal in interface Converter

Overrides:

unmarshal in class MapConverter

Parameters:

reader - The stream to read the text from.

Returns:

The resulting object.

unmarshalComparator
