Implementation

Future<Mailbox?> setMetaDataEntries(List<MetaDataEntry> entries) {
  final parts = <String>[];
  var cmd = StringBuffer()..write('SETMETADATA ');
  var entry = entries.first;
  cmd.write('"${entry.mailboxName}" (');
  for (entry in entries) {
    cmd
      ..write(' ')
      ..write(entry.name)
      ..write(' ');
    final value = entry.value;
    if (value == null) {
      cmd.write('NIL');
    } else if (_isSafeForQuotedTransmission(entry.valueText ?? '')) {
      cmd.write('"${entry.valueText}"');
    } else {
      cmd.write('{${value.length}}');
      parts.add(cmd.toString());
      cmd = StringBuffer()..write(entry.valueText);
    }
  }
  cmd.write(')');
  parts.add(cmd.toString());
  final parser = NoopParser(this, _selectedMailbox);
  Command command;
  if (parts.length == 1) {
    command = Command(parts.first);
  } else {
    command = Command.withContinuation(parts);
  }
  return sendCommand<Mailbox?>(command, parser);
