   throws DataConverterException

Get value of the specified generic type. For example if value is of type List use the following expression (using TypeToken) to extract:

 TypeToken<List<MyClass>> typeToken = new TypeToken<List<MyClass>>() {};
 List<MyClass> result = value.get(List.class, typeToken.getType());
