serializePayload method

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

  var byteOffset = offset;

  // field timeline
  var timelineEncoded = utf8.encode(message.timeline);
  var timelineSSize = timelineEncoded.length;
  byteData.setUint16(byteOffset, timelineSSize, imc.endianSer);
  byteOffset += 2;
  for (var b in timelineEncoded) {
    byteData.setUint8(byteOffset++, b);
  }
  // field predicate
  var predicateEncoded = utf8.encode(message.predicate);
  var predicateSSize = predicateEncoded.length;
  byteData.setUint16(byteOffset, predicateSSize, imc.endianSer);
  byteOffset += 2;
  for (var b in predicateEncoded) {
    byteData.setUint8(byteOffset++, b);
  }
  // field attributes
  var attributesEncoded = utf8.encode(message.attributes);
  var attributesSSize = attributesEncoded.length;
  byteData.setUint16(byteOffset, attributesSSize, imc.endianSer);
  byteOffset += 2;
  for (var b in attributesEncoded) {
    byteData.setUint8(byteOffset++, b);
  }

  return byteOffset - offset;
}
