Subject [jira] Commented: (JDO-615) MetaData specification API
Date Fri, 22 May 2009 17:45:46 GMT

    [ https://issues.apache.org/jira/browse/JDO-615?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12712180#action_12712180
] 

Craig Russell commented on JDO-615:
-----------------------------------

> I suggest renaming ComponentMetadata to TypeMetadata. 

I agree with this suggestion. Component is way too overloaded, and Type is precisely what
we are defining with this API.

> MetaData specification API

> 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.
