 /**
  * A ChainedFactory provides a way to use custom Converters that have access to the default
  * Converters. An example of use is to wrap incoming/outgoing json in a root object and delegate
  * then the ser/de to the default Converter.
  *
  * <p>This mechanism is internally used by Genson to decorate the different Converters with
  * additional behaviour (null handling, ser/de of polymorphic types with class info, runtime type
  * based ser/de, etc).
  *
  * <p>Note that you can't use it in situations where you want to start reading/writing some
  * partial infos and want to delegate the rest to the default Converter.
