[jira] Created: (TUSCANY-329) Simplified extension API improvements
Simplified extension API improvements
-------------------------------------
Key: TUSCANY-329
URL: http://issues.apache.org/jira/browse/TUSCANY-329
Project: Tuscany
Type: Improvement
Components: Java SCA Core
Versions: M1
Reporter: ant elder
Assigned to: Jim Marino
Priority: Critical
Fix For: M1
The work to create simple APIs for adding extensions has made some of the work required to add an extension much simpler, but there's still things that can be simplfied further for container extensions for new component types. The relevant classes are the ContextFactory, ComponentContext, and TargetInvoker which have a non trivial amount of code and its virtually identical for most simple components. A ComponentTargetInvoker would also be almost identical to the o.a.t.c.extension.ExternalServiceTargetInvoker. Code for these classes already exists in the Java container, it just needs to be refactored a little to be generic and moved to the o.a.t.c.extension package.
Be really great if we could get this done before M1 so we have stable extension APIs for people to work with.

------------------------------------
Hi Meeraj,
The doc on this is still lacking but did you notice the support classes in extensions under core? These handle many of the "common" cases? Also, I'm currently doing some work in the sandbox on simplifying the extension API further some your feedback on improvements to the extisting API (it's still very rough) would be great to hear.
Thanks,
Jim

---------------------------------------------
Jim,
I have refactored the Groovy implementation to use the extension support classes in core. I think, now the concrete implementation classes look a lot tidier. I have attached the files to the JIRA issue 317.

Meeraj Kunnumpurath commented on TUSCANY-329:
---------------------------------------------
Jim,
I have had a quick look at the support class. This is kind of what I thought about, define generic abstractions for the extension interfaces and have parameterization by the concrete types. I think, there are still issues around type casts between raw and generic types in the support classes. I will have a closer look tonight and get the groovy implementation to extend the support classes and see how it goes.

Attachment: AbstractImplementationLoader.java
Jim,
I have been trying to make the implementation loader generic, I have attached the file. It would be great, if you could please have a look. Also WireBuilderSupport seems to generic, however, the type doesn't seem to be used anywhere. Sould it be T extends TargetInvoker and the abstract method to return the type?
Thanks

---------------------------------------------
I noticed this working on the Groovy container. There was significant code duplication in the extension classes for component context, context factory builder and implementation builder.
Thanks

Jim Marino commented on TUSCANY-329:
------------------------------------
Cool - let me know how it goes. I'm looking to combine ContextFactory and AtomicContext as well, but after our milestone release (this will involve significant refactor to the scope containers). If you want to see some of the early work on this, check out the sandbox under sandbox/jboynes/sca. The extension points for bindings should remain the same though.
Let us know how things go for you tomorrow and if you have any questions or suggestions.
