Andy Jefferson updated JDO-615:
-------------------------------
Attachment: jdometadata-6.patch
javax.jdo.metadata package has been commited to SVN (trunk).
This patch is for the PMF methods - not committed since that will break
compilation where the implementation doesn't yet have these methods. Uses
newXXX instead of setXXX for single-valued props. Have followed java beans
pattern for most, with the exception of boolean fields that have a default, so
cannot be "unset". Maybe some attributes have been missed off - left as an
exercise to the reader :-)
I don't see much point in methods like newField() - nothing in our use-cases
require a FieldMetadata when we don't have the name of the field.

> Key: JDO-615
> URL: https://issues.apache.org/jira/browse/JDO-615
> Project: JDO
> Issue Type: New Feature
> Reporter: Andy Jefferson
> Fix For: JDO 2 maintenance release 3

> Attachments: jdometadata-6.patch

>
> We can specify MetaData via XML or annotations. The only way missing is via
> an API. I propose mirroring the XML structure with interfaces of the form
> public interface MetaData
> {
> addExtension(String key, String value);
> removeExtension(String key, String value);
> ...
> }
> public interface FileMetaData
> {
> addPackage(PackageMetaData pmd);
> ...
> }
> public interface PackageMetaData
> {
> addClass(ClassMetaData cmd)
> ...
> }
> public interface ClassMetaData
> {
> addField(FieldMetaData fmd)
> ...
> }
> public interface FieldMetaData
> {
> setInheritance(InheritanceMetaData inhmd)
> ...
> }
> and so on.
> We would then require a method on the PMF to register the metadata.
> If there are no objections to such a feature I'll propose a patch to try to
> provide all current JDO2 capabilities.
