Examples of org.geotools.feature.collection.AdaptorFeatureCollection

org.geotools.feature.collection.AdaptorFeatureCollection
Implement a feature collection just based on provision of iterator.
You will need to implement the following methods:
- {@link #getBounds()}
- {@link #size()}
- {@link #closeIterator(Iterator)}
- {@link #openIterator()}

    // A slightly faster implementation is to not create a new Feature each time in the iterator but wrap the
