how to combine jdo and acl.basics

[derKaiser]

hi

i'm currently thinking about how to combine the basicacl package and jdo.
but the object design of this package seems to be harmonizd with jdbc and designed jdo-unfriendly: Object relational frameworks should give back the programmer a more object-oriented feeling, by replacing objectidentities by the objects itself, right?:

public abstract class AbstractBasicAclEntry implements BasicAclEntry {
    private Object object; //instead of AclObjectIdentity aclObjectIdentity 
    private Object parent; //instead of AclObjectIdentity aclObjectParentIdentity
    private Object recipient;
    private int[] validPermissions;
    private int mask = 0;
}

so what would you recommend?

People have written Hibernate implementations of BasicAclExtendedDao, so I'm not sure the object design is that bad.

The reason BasicAclEntry.getAclObjectIdentity and BasicAclEntry.getAclParentObjectIdentity return an identifier Object - instead of the real domain object the BasicAclEntry represents - is because AclManager is already passed the domain object and we're only interested in its ACL information. It would be non-performant (not to mention more difficult to write BasicAclDao implementations) to require the BasicAclDao to re-retrieve the domain object.
