Changes in Objectify 4.0rc1

[Jeff Schnitzer]

I'm doing some final cleanup on the Objectify API gearing up for the official 4.0 release.

I haven't put 4.0rc1 in maven central yet, but I'd love it if some other people tried out master. There are some changes:

 * ObjectifyWrapper and LoaderWrapper are gone; instead there is a *much* simpler system whereby you can directly extend ObjectifyImpl and LoaderImpl. I have updated the Motomapia example to demonstrate this.

 * ofy().getTxn() -> ofy().getTransaction(). I have some nefarious future plans for a method ofy().txn() and I want to eliminate the ambiguity now.

 * ofy().getFactory() -> ofy().factory(). It reads more fluently.

 * ofy().toEntity() and ofy().toPojo() are now ofy().save().toEntity() and ofy().load().fromEntity(). This means you can have load groups when you load().fromEntity(), whereas you couldn't before.

In some of these cases I left the old methods and added @Deprecation flags; they will be removed fairly quickly.

I can't think of any other changes that cannot be put off to 4.1, so if this build passes muster, it's going to become 4.0.

This is now in Maven Central.

If I don't hear major complaints by Wednesday, I'm going to cut the official 4.0 release.

I think I just ran into a bug. Updated to 4.0rc1, and it seems to be present in that version.

I'm trying to filter using the IN operator on the 'id'; for the value, I'm passing an String[] of values. Objectify complains:

[INFO] Caused by: java.lang.IllegalArgumentException: Id filter values must be Long or String

[INFO] at com.googlecode.objectify.impl.QueryImpl.addFilter(QueryImpl.java:147)

[INFO] at com.googlecode.objectify.impl.QueryImpl.filter(QueryImpl.java:99)

[INFO] at com.googlecode.objectify.impl.QueryImpl.filter(QueryImpl.java:32)

Is this Objectify giving early warning of an appengine datastore limitation, or is it erroneously assuming filter values must always be a scalar?

Tried the same thing with an ArrayList<String>; same result.

BTW, this seems like it's another type of query that Objectify could optimize into a hybrid query. Does it?
