[cdi-dev] New builders API

[Martin Kouba]

Hi all,

me and Matej, we've already tried to explain some points in cdi/pull/287 
discussion. Anyway, we're going to release Weld 3.0.0.Alpha16 (base on 
2.0.Alpha4) later this week so that everyone can start playing with the 
new API. And we'd like to prepare some simple examples to help people 
get started as well.

Martin

> In the latter, it's clearer to a developer which attributes are required
> vs optional.  Builders typically use sensible defaults.  Maybe that was
> the intention here, but I couldn't really get that sense when converting
> over.  It also wasn't clear what to do when done.  I suspect I just
> leave it, but without some kind of closing "build()" or "done()" method,
> it becomes ambiguous.

> - Annotated*Configurator
> TBH, I have no idea what I was configuring in this one at the first
> pass.  I started with a method.  I wanted to replace the method's
> annotations.  It seemed like I could set that up using the configurator,
> but I ended up having to do setAnnotated at the end anyways, so I'm not
> sure what the configurator bought me.

> The one nice thing I saw was the simpler to use lambda functions.  Being
> able to stream through things like annotated method made the code much
> cleaner.

> For the open source code, I'll try to get some gists together that show
> the changes.  Maybe there's something I'm missing, so wouldn't mind a
> second set of eyes on the changes to see.
