@override Uint8List serialize()

Implementation

@override

  var buffer = Uint8List(size);
  var currentPos = 0;
  buffer.setRange(currentPos, currentPos + 4, intToBytes(primaryId, 4));
  currentPos += 4;
  buffer.setRange(currentPos, currentPos + 4, intToBytes(secondaryId, 4));
  currentPos += 4;
  buffer.setRange(currentPos, currentPos + 4, intToBytes(receipts.length, 4));
  currentPos += 4;
  sort();
  var res_receipts = ArrayHelpers.writeArray(buffer, receipts, currentPos);
  currentPos = res_receipts.item2;
  buffer = res_receipts.item1;
  return buffer;
