Re: [udig-devel] The new catalog method createTemporaryResource(FeatureT

[Jesse Eichar <jeichar@xxxxxxxxxxxxxxx>]

You just need a feature reader.  Here's a little example for you.   
(just psuedo code)

IGeoResource resource=catalog.createTemporaryResource( featureType );

FeatureStore store=resource.resolve( FeatureStore.class, monitor);
Feature[] feature=createCustomFeatures(); // note: feature's Feature  
Type must be == to featureType.
final Iterator<Feature> iter=Arrays.asList(feature).iterator();

store.addFeature( new FeatureReader(){
  public boolean hasNext(){  iter.hasNext(); }
  public Feature next() { iter.next(); }
  public void remove() { throw new UnsupportedOperationException() }
}

That's all you need.  Of course there are many variations on this as  
well.
