I am sorry we cannot do that ... the reason is that we need someone to *close*
the input stream (since it represents a live database connection sometimes).
As a result of this confusion (brought around in Java 5) we had to stop
extending Collection<Feature>.
Personally I recommend the use of visitor.
featureCollection.visit( new FeatureVisitor(){
public void accepts( Feature feature ){
... do stuff
}
}, progress );
Now in cases where the feature collection actually is in memory - you are
welcome to make use of whatever interfaces are available to you.
