serializePayload method

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

  var byteOffset = offset;

  // field contentType
  var contentTypeEncoded = utf8.encode(message.contentType);
  var contentTypeSSize = contentTypeEncoded.length;
  byteData.setUint16(byteOffset, contentTypeSSize, imc.endianSer);
  byteOffset += 2;
  for (var b in contentTypeEncoded) {
    byteData.setUint8(byteOffset++, b);
  }
  // field content
  var contentSSize = message.content.length;
  byteData.setUint16(byteOffset, contentSSize, imc.endianSer);
  byteOffset += 2;
  if (contentSSize > 0) {
    for (var b in message.content) {
      byteData.setUint8(byteOffset++, b);
    }
  }

  return byteOffset - offset;
}
