Subject [jira] Commented: (JDO-403) JDO2 Annotations
Date Sun, 21 Jan 2007 09:52:30 GMT

Andy Jefferson commented on JDO-403:
------------------------------------

Just remembered why I had Field.fieldType, Element.type, Key.type, Value.type as String instead
of Class. In the JDO2 spec we allow the implementation to support comma-separated sets of
possible values (in particular for when the user has a field of type Object with the intention
of storing some specific types there, or also with interface fields). We have 2 options to
fix this :-
1. Change the attribute back to type String and allow comma-separated like that
2. Add an additional attribute "fieldTypes" ("types" in Element, Key, Value) of type Class[].
With this the user could either set the "type" when using a single class (most common situation),
or use the "types" when specifying multiple.

Interface/Property also do not currently have annotations.

> It would be desirable for JDO2 to have its own set of annotations. We have developed
a set within JPOX that would likely serve as a starting point for such a set. In my opinion
they should be
> 1. Split into javax.jdo.annotations.jdo and javax.jdo.annotations.orm
> 2. Move ORM attributes from some of the JDO annotations and have a ORM annotation.
