[jira] Commented: (JDO-615) MetaData specification API
[ https://issues.apache.org/jira/browse/JDO-615?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12732091#action_12732091 ]
Renato Garcia commented on JDO-615:
-----------------------------------
I think IndexMetadata.getUnique has been changed by mistake here http://svn.apache.org/viewvc/db/jdo/branches/2.3-ea/api2/src/java/javax/jdo/metadata/IndexMetadata.java?view=diff&r1=737665&r2=724172&diff_format=u
/**
* Accessor for whether unique.
*
* @return Unique?
*/
- Boolean getUnique();
+ boolean getUnique();

> Key: JDO-615
> URL: https://issues.apache.org/jira/browse/JDO-615
> Project: JDO
> Issue Type: New Feature
> Components: api2, specification, tck2
> Reporter: Andy Jefferson
> Assignee: Craig Russell
> Fix For: JDO 2 maintenance release 3
>
> Attachments: BooleanProperties.patch, jdometadata-6.patch, lower-case-d-in-metadata.patch, type-2.patch, type.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.
