Thomas Vandahl commented on TORQUE-343:
---------------------------------------
Yes I know about the extensibility. The use case I have in mind is the
extension of persistent classes in a library like in Fulcrum Security. You are
supposed to extend e.g. user objects to match your requirements. Right now, we
always need to configure the OM class *and* its Peer class to handle this case.
It would be easier to query the Torque instance for the PeerImpl class for a
given OM class.
Another use case I found are complex queries. I found it very useful to define
separate (non-generated) PeerImpl/RecordMapper classes to handle complex joins
within custom-built objects. In the end I found myself up creating those
PeerImpl object instances over and over again because I had no real place to
store them. This is normally not necessary as these objects are thread safe.
to be continued...
> Implement a central registry for peerImpls like the registry for managers

> URL: https://issues.apache.org/jira/browse/TORQUE-343
> Project: Torque
> Issue Type: Improvement
> Components: Runtime, Templates
> Affects Versions: 4.0
> Reporter: Thomas Vandahl
> Assignee: Thomas Vandahl
> Fix For: 4.1
>
>
> I'd like to suggest a central registry for peerImpl-objects which can be
> queried by the Persistent class it is responsible for. This would allow
> reusing and extending the peer objects dynamically as well as giving them
> some kind of life-cycle.
> The main method would be similar to this:
> {code:java}
> public <T> BasePeerImpl<T> getPeerFor(Class<T> persistentClass)
> {
> return peerRegistry.get(persistentClass);
> }
> {code}
> I would also like to suggest moving the buildCriteria(obj) method to the
> RecordMapper or the TableMap class. This will further reduce the amount of
> code that needs to be generated.
> If the idea is received well, I'll come up with a proposal.
