Carsten Ziegeler commented on SLING-4275:
-----------------------------------------
I think we should try to resolve this issue, so let's look at them one by one
and start with the exceptions
[~radu.cotescu] I think we don't need a different runtime exception for each
and every service, even a Sightly runtime exception is not needed, a
SlingExeption is sufficient. Different runtime exception types make only sense
if the caller can do something about it - it's purpose should not be debugging
or having a meaningful exception type in the error log. So we should go with
one runtime exception but meaningful error messages (meaningful in the sense
that a human can do something with it)
> Review of the Sightly API
> -------------------------
>
> Key: SLING-4275
> URL: https://issues.apache.org/jira/browse/SLING-4275
> Project: Sling
> Issue Type: Task
> Components: Scripting
> Reporter: Carsten Ziegeler
> Fix For: Scripting Sightly Engine 1.0.0
>
>
> I have some comments about the public Sightly API:
> 1. There are several exceptions, like SightlyException,
> RuntimeExtensionException, SightlyUseException - are these really required?
> The API does not mention any method/interface throwing such an exception
> 2. RuntimeExtension and ExtensionInstance - I think we can get rid of the
> RuntimeExtension interface and simply pass the RenderContext in
> ExtensionInstance#call.
> 3. The purpose of the Record interface is a little bit unclear to me. In
> addition it has a T get(String) method while properties returns a
> Set<String>. I guess the engine supports a Map, so maybe we can get rid of
> this interface?
> 4. ResourceResolution seems to contain methods for getting scripts. Isn't
> this some functionalty the existing ServletResolver component provides? Or if
> not, shouldn't we move this to the Sling API?
> 5. Many of the methods in the RenderContext are Object traversal and value
> conversion methods. I think this needs to go into a separate service (and
> maybe package)
