Hi Adrian!
nice to see you involved here!
So, I took few time to reorganize my ideas and I would like to discuss
with you how to make a new [convert] component,.
For what I can see, the bigger part of the codebase has been kindly
borrowed from BeanUtils - which is fine - but, like always, I am
convinced we can give our users new experiences of using commons APIs.
Please take in consideration that I didn't gave any try and the
following below are random thoughts I had while driving to come back
home, so apologize in advance if something wouldn't sound correct.
* The first modification I'm proposing is about managing types
automagically - taking a look at GoogleGuice's TypeLyteral[1] it is
possible to understand that is possible to do some magic with Java
Generics, that would allow discovery types at runtime.
That would mean that converter types can be discovered at runtime -
without the users have to specify them - and that object type under
conversion can be discovered as well.
Guice code is licensed under ASL2.0 so parts could be extracted for our needs.
* The second proposal concerns about fluent APIs. Taking advantage
fromm the previous point, the existing pattern
getConverter( Class<?>, Class<?> ).convert( Object );
could be replaced by a fluent one:
<S, T> T convert( S ).to( Class<T> )
* The third proposal is about the loaders: IMHO the auto-loaders are
not so elegant and a ServiceLoader pattern would be more canonical -
and enough.
Anyway I like the public API to register converters - ServiceProvider
should not be a constraint - and we could modify them in a more fluent
way:
<S, T> convert( Class<S> ).to( Class<T> ).withConverter(
Converter<? extends S, ? extends T> )
So, what are your opinions/roadmaps about this component?
Many thanks in advance, all the best!
Simo
