You can do a select on the featuresource to get all data for the resource.
You can choose only to select the geometry column.
When you itterate over the records, you can extract the geometry from
This involves converting AGF data to GML (or whatever you prefer).
The basis for query to a featuresource, and extraction of geometry is
documented with an example in the developer guide (PDF version at least).
If you get stuck on the examples, please ask again.
