public class NullConverter extends AbstractConverter<Object,Object>
Converter implementation for handling null values. Returns
null when given a null source or null destination.
By running at Priority.EXTREMELY_HIGH, other converters should not
need to worry about null source or destination parameters.

Converter
Note that this does not necessarily entail that
Converter.convert(Object, Type) on a specific object of the given source
class will succeed. For example:
canConvert(String.class, List<Integer>) will return true
because a String can in general be converted to an Integer
and then wrapped into a List, but calling
convert("5.1", List<Integer>) will throw a
NumberFormatException when the conversion is actually attempted via
the Integer(String) constructor.

Object.toString() method instead). In the case of primitive types,
returns an object of the corresponding wrapped type. If the destination
type does not have an appropriate constructor, returns null.T - Type to which the object should be converted.src - The object to convert.dest - Type to which the object should be converted.public Class<Object> getOutputType()
