Subject [jira] Commented: (JDO-615) MetaData specification API
Date Fri, 22 May 2009 19:38:45 GMT

    [ https://issues.apache.org/jira/browse/JDO-615?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12712228#action_12712228

Michael Bouschen commented on JDO-615:
--------------------------------------

I agree with the renaming, TypeMetadata is the better name.

I tried your patch, but I could not apply the patch. Here is the error message:
  can't find file to patch at input line 18
  Perhaps you used the wrong -p or --strip option?
  The text leading up to this was:
  --------------------------
  |Index: TypeMetadata.java
  |===================================================================
  |--- TypeMetadata.java  (revision 776348)
  |+++ TypeMetadata.java  (working copy)

It looks like the patch misses the new interface TypeMetadata.

Can you please double check and create a new patch? Thanks.

> 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.
