> Key: ISIS-2064
> URL: https://issues.apache.org/jira/browse/ISIS-2064
> Project: Isis
> Issue Type: New Feature
> Components: Isis Applib (programming model)
> Reporter: Daniel Keir Haywood
> Priority: Minor
>
> as per dev mailing list
> [https://lists.apache.org/thread.html/9d766b4e43079f81d1a72c9a78be9f78f65433cb92288394b7f195df@%3Cusers.isis.apache.org%3E]
>
> We currently have the configuration property
> "isis.reflector.explicitAnnotations.action" which if specified requires
> @Action to be added as an annotation for all public methods that don't
> represent properties/collections or supporting methods. If this is enabled
> then there's generally no need to annotate public methods that aren't meant
> to be in the metamodel with the @Programmatic annotation.
>
> Andi and I have just been discussing this (off-list) and wondering if we
> should extend this in v2. Our idea is maybe to allow this to be specified at
> the class level, and to also have three levels rather than two:
>
> - explicit : all properties, collections and actions must be annotated
> - actions : actions must be annotated, but properties and collections need
> not. This is the behavior if the above configuration property is specified.
> - implicit : no annotations are required. This is the current default
>
> So, we were thinking to add a value to @DomainObject, eg
>
> @DomainObject(metamodelDiscoveryStrategy = EXPLICIT | ACTIONS | IMPLICIT |
> AS_CONFIGURED)
>
> where "AS_CONFIGURED" would read a new configuration property that would
> take these three values (replacing the existing
> "isis.reflector.explicitAnnotations.action".
>
> Two questions:
>
> 1. is the idea of a new level to explicitly annotate everything (properties
> and collections as well as actions) useful ?
> 2. is there a need to configure this on a class-by-class basis, or is a
> global configuration property sufficient?
