Retrieving SDO Types?

Is there a way that I'm missing to retrieve all of the SDO Types
associated with a certain URI? We're doing this today in the DAS by
diving down to EPackage, but would prefer having some sort of utility
to do this in SDO.

Perhaps this is something that should be considered for TypeHelper in
a future version of the spec?

Frank,

  That would be great. I'll open a low priority JIRA to track it.

Brent. It would be trivial to add such a method in SDOUtil, if you really 
need it.

Re: Retrieving SDO Types?

Posted by Brent Daniel <br...@gmail.com>.
Traversing from the Types we have to figure out the Types we don't
have seems a lot harder than having a utility in SDO that tells us all
of the Types for a URI. But, yes, that's possible.

If we have Customer then don't we also have the related Order and 
Address Types?

Re: Retrieving SDO Types?

This would disallow the scenario where you have a static model with
customers, address, and orders,  read some customers and addresses,
and then want to create a new order and associate it with a customer.
At least, you wouldn't be able to create it off the dynamic root.

Re: Retrieving SDO Types?

Posted by Kevin Williams <ke...@qwest.net>.
I ran this by Steve Brodsky and he suggested that we might be better off 
looking up the needed Types from the TypeHelper by the name as needed 
rather than asking for all types associated with the URI.  We can use 
the names we retrieve from ResultSetMetadata and it seems like this will 
simplify the code a bit since the processing for Static Type scenarios 
can be nearly identical to the Dynamic Type scenarios.  The 'aliasing' 
mechanism should still work too.

What do you think?
