Commenti

I WriteStartObjectmetodi , WriteObjectContente WriteEndObject devono essere implementati. I tre metodi vengono usati in successione per scrivere la serializzazione completa usando il modello: inizio scrittura, scrittura contenuto e fine scrittura. Se l'implementazione scrive utilizzando elementi XML, gli attributi possono essere inseriti prima di scrivere il contenuto dell'oggetto. I tre metodi vengono chiamati anche dall'implementazione virtuale del WriteObject metodo .
