serializePayload method

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

  var byteOffset = offset;

  // field origin
  var originEncoded = utf8.encode(message.origin);
  var originSSize = originEncoded.length;
  byteData.setUint16(byteOffset, originSSize, imc.endianSer);
  byteOffset += 2;
  for (var b in originEncoded) {
    byteData.setUint8(byteOffset++, b);
  }
  // field text
  var textEncoded = utf8.encode(message.text);
  var textSSize = textEncoded.length;
  byteData.setUint16(byteOffset, textSSize, imc.endianSer);
  byteOffset += 2;
  for (var b in textEncoded) {
    byteData.setUint8(byteOffset++, b);
  }

  return byteOffset - offset;
}
