resource - The resource to marhsall the object to

root - The Object to marshall to the resource

mapping - The mapping definition of how to marshall the Object to the resoruce

unmarshall

public Object unmarshall(Resource resource,
                         Mapping mapping,
                         MarshallingContext context)

Description copied from interface: Converter

Unmarshall the given Resource to the appropiate Object.

Specified by:

unmarshall in interface Converter

Parameters:

resource - The resource to unmarshall into an Object

mapping - The mapping definition of how to unmarshall the Resource into an Object

handleNulls

protected boolean handleNulls(MarshallingContext context)

Should the converter handle nulls? Handling nulls means should the converter process nulls or not. Usually the converter will not persist null values, but sometimes it might be needed (MarshallingContext.handleNulls()).

Extracted to a method so special converters can control null handling.

Parameters:

context -

Returns:

true if the converter should handle null values
