I'm not entirely certain what you are asking, but while Objectify
doesn't have a special annotation that will turn a field into a
protobuf, you can pretty easily do this yourself with @PostLoad and
@PrePersist lifecycle callbacks:
class MyEntity {
@Transient ComplexThing thing;
byte[] thingBuf;
@PrePersist void onSave() { thingBuf = pbfSerialize(thing); }
@PostLoad void onLoad() { thing = pbfDeserialize(thingBuf); }
}
