serializePayload method

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

  var byteOffset = offset;

  // field command
  byteData.setUint8(byteOffset, message.command.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 goalXml
  var goalXmlEncoded = utf8.encode(message.goalXml);
  var goalXmlSSize = goalXmlEncoded.length;
  byteData.setUint16(byteOffset, goalXmlSSize, imc.endianSer);
  byteOffset += 2;
  for (var b in goalXmlEncoded) {
    byteData.setUint8(byteOffset++, b);
  }

  return byteOffset - offset;
}
