示例1: ParseDirectory
void JamendoService::ParseDirectory(QIODevice* device) const {
int total_count = 0;
// Bit of a hack: don't update the model while we're parsing the xml
disconnect(library_backend_, SIGNAL(SongsDiscovered(SongList)),
library_model_, SLOT(SongsDiscovered(SongList)));
disconnect(library_backend_, SIGNAL(TotalSongCountUpdated(int)), this,
SLOT(UpdateTotalSongCount(int)));
// Delete the database and recreate it. This is faster than dropping tables
// or removing rows.
library_backend_->db()->RecreateAttachedDb("jamendo");
TrackIdList track_ids;
SongList songs;
QXmlStreamReader reader(device);
while (!reader.atEnd()) {
reader.readNext();
if (reader.tokenType() == QXmlStreamReader::StartElement &&
reader.name() == "artist") {
songs << ReadArtist(&reader, &track_ids);
}
if (songs.count() >= kBatchSize) {
// Add the songs to the database in batches
library_backend_->AddOrUpdateSongs(songs);
InsertTrackIds(track_ids);
total_count += songs.count();
songs.clear();
track_ids.clear();
// Update progress info
app_->task_manager()->SetTaskProgress(load_database_task_id_, total_count,
