Examples of org.geotools.data.simple.SimpleFeatureCollection.features()

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(); } 
```

        assertTrue(expectedBounds.boundsEquals2D(grid.getBounds(), TOL));


        boolean[] flag = new boolean[expectedNumElements + 1];
        int count = 0;


        SimpleFeatureIterator iter = grid.features();
        try {
            while (iter.hasNext()) {
                SimpleFeature f = iter.next();
                int id = (Integer) f.getAttribute("id");
                assertFalse(id == 0);
