serializePayload method

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

  var byteOffset = offset;

  // field sysName
  var sysNameEncoded = utf8.encode(message.sysName);
  var sysNameSSize = sysNameEncoded.length;
  byteData.setUint16(byteOffset, sysNameSSize, imc.endianSer);
  byteOffset += 2;
  for (var b in sysNameEncoded) {
    byteData.setUint8(byteOffset++, b);
  }
  // field sysType
  byteData.setUint8(byteOffset, message.sysType.value);
  byteOffset += 1;
  // field owner
  byteData.setUint16(byteOffset, message.owner, imc.endianSer);
  byteOffset += 2;
  // field lat
  byteData.setFloat64(byteOffset, message.lat, imc.endianSer);
  byteOffset += 8;
  // field lon
  byteData.setFloat64(byteOffset, message.lon, imc.endianSer);
  byteOffset += 8;
  // field height
  byteData.setFloat32(byteOffset, message.height, imc.endianSer);
  byteOffset += 4;
  // field services
  var servicesEncoded = utf8.encode(message.services);
  var servicesSSize = servicesEncoded.length;
  byteData.setUint16(byteOffset, servicesSSize, imc.endianSer);
  byteOffset += 2;
  for (var b in servicesEncoded) {
    byteData.setUint8(byteOffset++, b);
  }

  return byteOffset - offset;
