Re: Important changes
Hi there,
I took a stab at TAMAYA-355, the multi-value mapping ticket, and had a question.
Anatole, you mention that there's somewhere in core that supports mapping that includes nested elements, but I can't find it. Where did you mean? I've got the json and yaml extensions found, but am missing that XML-looking config format in the ticket.
I'm excited that we're pushing towards another release. :-)

Hi guys,
I have added three ticket I like to be discussed, which I think together
with other open issues would be a good package for the next release. So
have a look at and comment on:
https://issues.apache.org/jira/browse/TAMAYA-355
https://issues.apache.org/jira/browse/TAMAYA-354
https://issues.apache.org/jira/browse/TAMAYA-353
<https://issues.apache.org/jira/browse/TAMAYA-353>

Hi all,
multi-value support looks more difficult as it first seems.
The current approach allowed to add collections of more or less SIMPLE
items into a single key.
But even thinking on being capable of replacing backends currently written
in *xml, json, yam *completely, we actually have a requirement for being
able to support lists (or arrays) in multiple locations within a property
key, e.g. something like:
a.b[0].c.d[0].name
, where b and c are array structures. This is what I could successfully
implement on the formats module. Nevertheless this structure matches
with Map<String,String>, nevertheless there is the question of internal
representation during evaluation phase from the various PropertySources.
Actually property sources basically provide a Map<String,PropertyValue>.
After a number of experiments I suggest changing PropertyValue to an
interface and also extend that interface with an additional ListPropertyValue
actually allows to implement something similar without blowing up all other
API/SPIs completely. I am currently finishing this kind of experiment and
will create a corresponding branch for discussion until Wednesday the
latest. Based on that, we probably have to discuss the collection support
completely. E.g. one idea would be to use our functional extension points,
e.g. something similar like
List<Map> beans = Configuration.adapt(TamayaCollections.asList( Map.class,
"a.b"));
Or mapped to a concrete configuration bean class:
List<Bean> beans =
Configuration.adapt(TamayaCollections.asList(Bean.class, "a.b"));
This would transfer and map the properties in the a.b array to instances of
the given class.

So I guess we try go get Tamaya graduated here eventually?
If a clarification of a more distinct config spec than the "Trinity" that's
cultivated right now happens before that, it certainly won't hurt ;-)
@Anatole All the best.

Hi William
Ill make ir short, since I am a bit sick today...
As of now the format modules do not support things, like Json arrays and
Yaml lists properly. There is another ticket for that.
Actually I have implemented this ticket already, but not yet committed,
because I also was playing around with another other ticket for better
classloading support (I know mixing up tickets is bad practice, ashes on my
head)...
I think I will be back to notmal soon, so I can create a branch...
Ok? J Anatole
