Nome: SongSummaryDTO.java Autore: VT.G Licenza: GNU GPL v3 Data Creazione: 13 Febbraio 2011 Tipo, obiettivo e funzione del componente: Come tutte le altri classi di questo package questa classe permette lo scambio di informazioni tra client e server all'interno delle chiamate RPC. Contiene e rappresenta i dati più comunemente utilizzati di un brano, ovvero quelli che vengono visualizzati in una playlist all'interno di un profilo.


        List<String> playlists = new ArrayList<String>();
        for (PlaylistDTO tmp : current_user.getMusicLibrary().getPlaylists()) {
            int real_size = 0;
            for (String tmp2 : tmp.getSongList()) {
                SongSummaryDTO song = current_user.getMusicLibrary().getSongs()
                        .get(tmp2);
                if (song != null) {
                    if (!song.getTitle().equals("")) {
                        real_size++;
                    }
                }
            }
            playlists.add(tmp.getName() + " (" + real_size + ")");
