Class org.geotools.feature.FeatureCollection

Examples of org.geotools.feature.FeatureCollection.features()

org.geotools.feature.FeatureCollection.features()
Obtain a FeatureIterator
of the Features within this FeatureCollection.
The implementation of FeatureIterator must adhere to the rules of fail-fast concurrent modification. In addition (to allow for resource backed collections) the FeatureIterator.close() method must be called.
Example use:
```
 FeatureIterator iterator=collection.features(); try { while( iterator.hasNext()  ){ Feature feature = iterator.next(); System.out.println( feature.getID() ); } } finally { iterator.close(); } 
```
GML Note: The contents of this iterator are considered to be defined by featureMember tags (and/or the single allowed FeatureMembers tag). Please see getFeatureType for more details.
@return A FeatureIterator.
