I have committed some new contribution services interfaces under
revision #
525071 that would better align the contribution service module with the
SCDL4J proposals. Note that some of these interfaces, that would be
used for
artifact resolving, will need to be implemented by the Assembly model
classes.
Please take a look at these interfaces and let me know what you guys
think,
I plan to polish them little bit more tomorrow, and then start
integrating
it with the other modules and the embedded runtime.
Thoughts ?
Thanks. I'll try to implement the ArtifactProcessors and ModelResolvers
for SCA XML assembly files in the modules/assembly module.
I am assuming that the ArtifactProcessor.read() method will contain the
logic currently in the loaders, then I'll move the logic from
CompositeUtil to the ArtifactProcessor.resolve() and
ArtifactProcessor.normalize() methods. I added a little earlier today
that normalize method to your ArtifactProcessor interface, to cover the
3rd of the 3 phases I was describing in [1].
[1] http://www.mail-archive.com/[email protected]/msg16229.html
Here's an outline of how I'm planning to implement the ArtifactProcessor
interface:
- read will read the model in memory, from a StAX XMLStreamReader
- resolve will resolve pointers to other models, calling back to the
Contribution to find the referenced artifacts
- normalize will apply policies at the various levels, propagage and
merge component/service/reference configuration declarations from the
bottom (componentType/constrainingType) to the top (composite/component)
of the hierarchy. I'll probably just do the strict minimum here for now
just to get going.
Does that makes sense?
Now some questions:
- The assembly module deals with 3 types of files, .componentType,
.constrainingType, .composite. Does that mean I have to implement 3
ArtifactProcessors?
- If the answer is yes, how do I associate a particular
ArtifactProcessor with a file type?
