Question about obtaining a projection of a SpecificRecord

["Farkas, Zoltan" <Zo...@pimco.com>]

  public static  GenericData.Record project(final SpecificRecord object, final Schema projectionSchema)
          throws IOException {
    ByteArrayBuilder bab = new ByteArrayBuilder(128);
    DatumWriter<T> writer = new SpecificDatumWriter<>((Class<T>) object.getClass());
    Encoder encoder = EncoderFactory.get().binaryEncoder(bab, null);
    writer.write(object, encoder);
    encoder.flush();
    DatumReader<Object> reader = new GenericDatumReader<>(object.getSchema(), projectionSchema);
    DecoderFactory decoderFactory = DecoderFactory.get();
    Decoder decoder = decoderFactory.binaryDecoder(new ByteArrayInputStream(bab.getBuffer(), 0, bab.size()), null);
    return (GenericData.Record) reader.read(null, decoder);
  }

Is there a better way to obtain a projection of a SpecificRecord?  The se/derialization to byte[]  seems unnecessary...

Let me know,

Thank you
