Re: [udig-devel] Remove temporary resource from catalog
I don't know if this may also help ( i wild guess for sure) but I will share it anyway,I have stumbled upon this code in MapEditor.java


private void removeTemporaryLayers( IPreferenceStore store ) {
        if (store
                .getBoolean(net.refractions.udig.project.preferences.PreferenceConstants.P_REMOVE_LAYERS)) {
            List<Layer> layers = getMap().getLayersInternal();
            List<Layer> layersToRemove = new ArrayList<Layer>();
            for( Layer layer : layers ) {
                if (layer.getGeoResources().get(0).canResolve(ITransientResolve.class)) {
                    layersToRemove.add(layer);
                }
            }

            if (!layers.isEmpty()) {
                if (getMap().eResource() != null)
                    getMap().eResource().setModified(true);
                layers.removeAll(layersToRemove);
            }
        }
    }


Best regards,

Hey Jesse,

thanks for your help. Here the solution if anyone is having the same issue:

private final String LAYERNAME = "GridViewLayer";
private final String LAYERURL = "http://localhost/scratch#"
                       + this.LAYERNAME;

SimpleFeatureTypeBuilder tb = new SimpleFeatureTypeBuilder();
tb.setName(LAYERNAME);
SimpleFeatureType sft = tb.buildFeatureType();
IGeoResource resourcex CatalogPlugin.getDefault().getLocalCatalog().createTemporaryResource(sft);


// later on

List<IResolve> list = CatalogPlugin.getDefault().getLocalCatalog().find(new URL(LAYERURL), new NullProgressMonitor());
if(!list.isEmpty()){
 IGeoResource geo = (IGeoResource) list.get(0);
 IService service = geo.service(new NullProgressMonitor());
 ActiveMemoryDataStore resolve = service.resolve(ActiveMemoryDataStore.class, new NullProgressMonitor());
 resolve.removeSchema(LAYERNAME);
}

Thanks again!

Kon
