org.geotools.data.simple.SimpleFeatureCollection.features()
Obtain a SimpleFeatureIterator of the Features within this SimpleFeatureCollection.
The implementation of FeatureIterator must adhere to the rules of fail-fast concurrent modification. In addition (to allow for resource backed collections) the SimpleFeatureIterator.close() method must be called.
Example use:
```
 SimpleFeatureIterator iterator=collection.features(); try { while( iterator.hasNext()  ){ SimpleFeature feature = iterator.next(); System.out.println( feature.getID() ); } } finally { iterator.close(); } 
```

      
        SimpleFeatureSource fsLine = (SimpleFeatureSource) layers.get(getLineTypeRef());
        if(fsLine == null)
          return true;
        SimpleFeatureCollection fcLine = fsLine.getFeatures();
        SimpleFeatureIterator fLine = fcLine.features();
        
        SimpleFeatureSource fsPoly = (SimpleFeatureSource) layers.get(getRestrictedPolygonTypeRef());
        if(fsPoly == null)
          return true;
        ListFeatureCollection fcPoly = new ListFeatureCollection( fsPoly.getFeatures() );
