| Re: [tigerstripe-dev] Using annotations.... |
So, I am trying to make use of the Annotations framework from Tigerstripe...
I declared an OclConstraint annotation with 3 attributes (type, description and constraint).
I then used the annotation from Tigerstripe in a plugin:
#foreach ($entity in $entities)
Here...
$entity.Name | $entity.getAnnotations("tigerstripe")
#set($ocl = $entity.getAnnotations("tigerstripe"))
#foreach ($o in $ocl)
-> $o.content.language
-> $o.content.description
-> $o.content.constraint
#end
This is hardly user friendly. Looking in the implementation of org.eclipse.tigerstripe.annotation.core.Annotation and org.eclipse.tigerstripe.workbench.internal.core.model.ArtifactComponent
I see the following issues:
1) Annotation just contains the URI of the annotated object and the annotation itself. There is no information about what the annotation is. What I actually want to do is something like:
#set($anno = $entity.getAnnotations("tigerstripe"))
#foreach ($a in $anno)
#if ($a.type == "OclConstraint)
-> $a.content.language
-> $a.content.description
-> $a.content.constraint
#end
#end
2) I also want to get able to directly access an annotation:
#set($ocl = $entity.getAnnotation("tigerstripe","OclConstraint"))
-> $ocl.language
-> $ocl.description
-> $ocl.constraint
--> Should throw an exception if more than one defined...
#set($ocls = $entity.getAnnotations("tigerstripe","OclConstraint"))
These should both return the annotation content, rather than the annotation itself.
Recommended Fix:
1) Add annotationType field to the Annoation object and populate it with the model object name (maybe need more that this? - the annotation URI?)
2) Modify the methods in AbstractComponent as described above.
I will raise bugzillas for this..
