Subject [jira] Commented: (JDO-510) Remove @Field and @Property and replace them with @Persistent
Date Mon, 23 Jul 2007 06:35:31 GMT

    [ https://issues.apache.org/jira/browse/JDO-510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12514571

Craig Russell commented on JDO-510:

I agree. We can add a Persistent[ ] members() default {} to @PersistenceCapable to do this
easily enough. We can use the @Persistent(name="superclassName" ...) with whatever overrides
are needed. 

But note that the spec doesn't allow for changing the persistenceModifier of a superclass
field or property. From 18.15, " The persistence-modifier attribute can be specified only
for fields declared in the Java class, and not fields inherited from superclasses. " But mapping
certainly can be overridden.

> Annotations are different from xml ways that make it impossible to refer to persistent
fields and properties in the same way. We started out thinking that we could simply map the
xml field to annotations @Field and xml property to @Property but could not refer to multiples
in a sane way.
> This change removes @Field and @Property and replaces them with @Persistent. Other annotations
that refer to these are changed so that they refer to members instead of to fields or properties.
