public SimpleFeatureIterator features()
SimpleFeatureCollectionThe 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();
}
features in interface SimpleFeatureCollectionfeatures in interface FeatureCollection<SimpleFeatureType,SimpleFeature>features in class DecoratingSimpleFeatureCollectionpublic SimpleFeatureCollection subCollection(Filter filter)
FeatureCollectionThe contents of the returned SimpleFeatureCollection are determined by applying the provider Filter to the entire contents of this FeatureCollection. The result is "live" and modifications will be shared.
This method is used cut down on the number of filter based methods required for a useful SimpleFeatureCollection construct. The FeatureCollections returned really should be considered as a temporary "view" used to control the range of a removeAll, or modify operation.
Example Use:
collection.subCollection( filter ).clear();
The above recommended use is agreement with the Collections API precident of List.subList(
start, end ).

FeatureCollectionThis method may not be supported by all implementations, consider the use of FeatureSource.features( Query ).
