[udig-devel] How to avoid LayerResource cache?

[Jody Garnett <jgarnett@xxxxxxxxxxxxxxx>]

Hi Jesse; the CSV library I am using is "streaming" based .... ie I can 
get a single use API which I need to close after each use.
>         CsvReader pr = null;
>         try {
> ....
>             if( resource instanceof LayerResource ){
>                 resource = 
> CatalogPlugin.getDefault().getLocalCatalog().getById(IGeoResource.class, 
> resource.getIdentifier(), null );
>             }
>             pr = resource.resolve(CsvReader.class, new 
> SubProgressMonitor(monitor, 10) );
>     ...
>             }
>         } catch (IOException e) {
>             throw new RenderException(e); // rethrow any exceptions 
> encountered           
>         }
>         finally {
>             if( pr != null ) pr.close();
>             monitor.done();
>         }
Right now I had to do an amazing trick to find the real resource; the 
LayerResource would cache the instance being made and return it to me 
each time; even after I had already closed it.

Do you have any suggestions for this one? This is training material so ...
- I don't want to break out another class; I would like to use the 
CsvReader as provided
- The catalog lookup shown above is a bit of a crazy hack; not sure I 
want to explain it to myself let alone others...
- Is there a way to "turn off" LayerResource cache? Or only have it 
cache known things ...
