Shai Erera commented on LUCENE-2310:
------------------------------------
That was usually the approach. You provide new methods, deprecate old ones,
however both work and not in a XOR mode. Both should work and we need to ensure
that if people call both they still function properly. Unless this has changed,
in which case it should be clearly documented.
But I don't think it is a big problem to support both? If Document still keeps
its fields in a List then all should remain the same. We could have a 4.0 note
to switch to a Map based DS to better support remove, but that's questionable
because we'll need to maintain ordering on the fields (the order in which they
inserted) though personally I don't think it should matter much to the user,
however that's the current implementation.

> In order to move field type like functionality into its own class, we really
> need to try to tackle the hierarchy of Fieldable, AbstractField and Field.
> Currently AbstractField depends on Field, and does not provide much more
> functionality that storing fields, most of which are being moved over to
> FieldType. Therefore it seems ideal to try to deprecate AbstractField (and
> possible Fieldable), moving much of the functionality into Field and
> FieldType.
