Hey Steve,
Thanks for the answer.
I was aware of these two solutions but there are definitely projects which
want to use DTO projections and cannot (don't) want to utilize neither the
annotation nor the native Hibernate API.
I think using the approach I mentioned would be beneficial, at least I see
the potential.
Do you think if we implement this it would violate some contract or do you
see anything which prevents us from supporting this?
It's not a question of whether we *can* do this. Its programming...
essentially anything is possible. Its a question of whether it makes
sense. And I personally am not sure this does conceptually, although I
will for sure listen to other opinions.
At the very least however I am not even going to consider this in 5.x
And btw... you say you do not want to use the native Hibernate APIs yet you
want to use some Hibernate-specific feature beyond the spec. Assuming the
desire to not use the Hibernate APIs is to allow for that completely
pie-in-the-sky idea of provider portability adding this feature actually
introduces a unequivocally worse situation. At least when you use the
Hibernate-specific APIs you will get a compile-time error when you switch
vendors; but using this proposed feature you'd only get such a error at
runtime - and you'd still have the problem of how to solve this in the new
provider...
