RE: [dali-dev] Manipulate java resources via resource model

["Dimitrov, Dimiter" <d.dimitrov@xxxxxxx>]

Hi Brian,

 

I will take a look and I will ask you if something is not clear to me. Just another question at this stage. When I change the model, whether change will be propagated directly in the source, or I have to save the explicitly. If I have to do it explicitly, is there special API provided from DALI, or I have to use JDT API?

 

Best Regards,

Dimiter

Yes, Member is the interface Dali uses to manipulate annotations in Java source code.
We use implementations of AnnotationAdapter and DeclarationAnnotationAdapter to
add, remove, and change annotations on a member (type, field, or method).
These adapters are public while the implementations are still internal; but you can look
at the implementations to see how we manipulate annotations ourselves.

Ask, if something is not clear, and I will try to remember how it works. :)

Hello,

In our work with new JPA model, we have necessity to manipulate java entity class, adding new fields and annotations. We could do this via JDT API, but I’m wondering whether will be possible to do this via java resource model? I mean if we have reference to JavaResourcePersistentType (respectively to its fields and properties) could we manipulate them? For instance is it possible to add relation one to one on attribute with name attribute? I hope that the presented API provide such opportunities, because I noticed method getMember() (for type, field or property), which returns Member. From own side Member (in accordance with Java Doc) offers manipulating of annotations on members. Is this manipulation provides modifying (reflected in the code), or it is read-only?

Any help, information or hint will be appreciated.
