serializePayload method

@override int serializePayload(TrexOperation? message, ByteData byteData, int offset)

Call to serialize only the payload, no header, returns a int with a serialized size

Implementation

@override
int serializePayload(
    imc.TrexOperation? message, ByteData byteData, int offset) {
  if (message == null) return 0;

  var byteOffset = offset;

  // field op
  byteData.setUint8(byteOffset, message.op.value);
  byteOffset += 1;
  // field goalId
  var goalIdEncoded = utf8.encode(message.goalId);
  var goalIdSSize = goalIdEncoded.length;
  byteData.setUint16(byteOffset, goalIdSSize, imc.endianSer);
  byteOffset += 2;
  for (var b in goalIdEncoded) {
    byteData.setUint8(byteOffset++, b);
  }
  // field token
  if (message.token == null) {
    byteData.setUint16(byteOffset, imc.ImcId.nullId, imc.endianSer);
    byteOffset += 2;
  } else {
    var id = message.token!.msgId;
    var pMsgSerializer = imc
        .messagesSerializers[imc.idsToMessages[id] ?? imc.ImcId.nullId]
        ?.call();
    if (pMsgSerializer != null) {
      byteData.setUint16(byteOffset, id, imc.endianSer);
      byteOffset += 2;
      var mPSize = pMsgSerializer.serializePayload(
          message.token, byteData, byteOffset);
      byteOffset += mPSize;
    }
  }

  return byteOffset - offset;
