Subject [jira] Created: (JDO-615) MetaData specification API
Date Fri, 21 Nov 2008 09:08:44 GMT
MetaData specification API
--------------------------

                 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


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.
