--------------------------------------
Labels: sd-candidate (was: )
> Formalize reuse of registered services
> --------------------------------------
>
> Key: NETBEANS-4795
> URL: https://issues.apache.org/jira/browse/NETBEANS-4795
> Project: NetBeans
> Issue Type: New Feature
> Components: platform - Lookup
> Affects Versions: 11.3
> Reporter: Svatopluk Dedic
> Assignee: Svatopluk Dedic
> Priority: Major
> Labels: sd-candidate
>
> During {{commit-validation}} cleanup, I've found out that it's relatively
> commont to *reuse other module services* in layer registration. The most
> reused was HTML completion provider, Word completion provider. But also Java
> Indexer was reused in Groovy.
> Currently this is done by *hardcoding classname* of the original provider
> implementation - but for example {{HtmlCompletionProvider}} is not a public
> API. Well, now it is, since if the class was moved, all web scripting modules
> would fail to complete tags.
> Another approach is to use *shadow to filename*, which is again not an API.
> In the case of Java Indexer, the filename has changed because manual XML
> registration was replaced by an annotation - with an undefined (impl-class
> based) filename generation).
> For these cases, I would like to have {{id}} attribute introduced for service
> providers, which would declare that the *id* is part of the module public
> API: the filename will be then formed as *serviceclass-modulecnb-id* to be
> stable and moderately unique. The annotation processor could check that (for
> NB modules; or maybe as a part of the documentation build step ?), the ID is
> mentioned in {{arch.xml as an supplemental API.}}
> For reference, I'd like to introduce an annotation, which would register *a
> foreign implementation*, so e.g. package-info.java could be annotated as with
> the templates. The reference would contain attributes
> * module CNB
> * service class
> * ID
> * optional true/false
> The Processor would ensure that the appropriate dependency is declared (weak
> = Recommends, otherwise Needs), that the target exists AND is indeed a
> declared API (perhaps an articial attribute in the layer).
