Hi,
We had discussions on this ML before on how to support SCDL extensibility
elements which are not part of the base SCDL model and are used in SCDL for
<xsd:any/>.
Let's use <import.sdo> as an example to illustrate my proposal.
1) ImportSDOLoader is a StAXElementLoader to load <import.sdo> element into
ImportSDO model object.
2) The model object is attached to the parent model object which is
CompositeComponentType in this case. We can use ModeObject.getExtensions()
to keep the models loaded from the extensibility elements.
3) Add a GenericBuilder interface and GenericBuidlerExtension in SPI as
follows:
public interface GenericBuilder<S extends SCAObject, M extends ModelObject>
{
S build(SCAObject parent, M modelObject, DeploymentContext
deploymentContext) throws BuilderException;
}
4) Change the Buidler and BuilderRegistry interface to support
GenericBuilder.
5) Create an ImportSDOBuilder which will create HelperContext from the
ImportSDO model.
6) When the BuilderRegistery builds Component/Service/Reference, we look at
the extensions for the corresponding model objects and try to run the
GenericBuilders against the objects in ModelObject.getExtensions().
7) The ImportSDOBuilder creates a AtomicComponent to wrap HelperContext. and
register it in the composite so that the component impl can use @Reference
(autowire=true) to get access to this HelperContext.
If we agree I'm on track with the overall direction, I'll work on it.
Thanks,
Raymond
