Class Summary

Class	Description
AbstractFeatureCollection	Implement a feature collection just based on provision of an Iterator.
AbstractFeatureVisitor	An abstract class to reduce the amount of work needed when working with FeatureVisitor.
AdaptorFeatureCollection	Implement a feature collection just based on provision of iterator.
BaseFeatureCollection<T extends FeatureType,F extends Feature>	Implement a feature collection just based on provision of a FeatureIterator.
BaseSimpleFeatureCollection
BridgeIterator<F extends Feature>	A closeable iterator wrapped around a provided feature iterator.
ClippedFeatureCollection	SimpleFeatureCollection wrapper that clip (crops) features according to the clip geometry passed.
ClippedFeatureIterator	SimpleFeatureIterator wrapper that clip (crops) features according to the clip geometry passed.
ClippingFeatureCollection	The class decorates a SimpleFeatureCollection with one that returns features that intersect the geometry passed with a Hints.GEOMETRY_CLIP
ClippingFeatureIterator	Decorates a SimpleFeatureIterator with one that return features if intersect the Geometry passed with the Hint.GEOMETRY_CLIP
DecoratingFeatureCollection<T extends FeatureType,F extends Feature>	A FeatureCollection which completely delegates to another FeatureCollection.
DecoratingFeatureIterator<F extends Feature>	A feature iterator that completely delegates to another FeatureIterator.
DecoratingSimpleFeatureCollection	A FeatureCollection which completely delegates to another FeatureCollection.
DecoratingSimpleFeatureIterator	A feature iterator that completely delegates to a normal Iterator, simply allowing Java 1.4 code to escape the caste (sic) system.
DelegateFeatureIterator<F extends Feature>	A feature iterator that completely delegates to a normal Iterator, simply allowing Java 1.4 code to escape the caste (sic) system.
DelegateSimpleFeatureIterator	A feature iterator that completely delegates to a normal Iterator, simply allowing Java 1.4 code to escape the caste (sic) system.
FeatureIteratorImpl<F extends Feature>	A convenience class for dealing with wrapping a Collection Iterator up as a FeatureIterator.
FilteredIterator<F extends Feature>	Provides an implementation of Iterator that will filter contents using the provided filter.
FilteringSimpleFeatureCollection	Decorates a feature collection with one that filters content.
FilteringSimpleFeatureIterator	Extension of FilteringFeatureIterator that type narrows to SimpleFeature.
MaxFeaturesSimpleFeatureIterator	SimpleFeatureIterator wrapper which can use a start and end bounds to cap the number of returned features.
MaxSimpleFeatureCollection	SimpleFeatureCollection wrapper which limits the number of features returned.
PushBackFeatureIterator<F extends Feature>	A feature iterator allowing to push back one feature
SimpleFeatureIteratorImpl	A convenience class for wrapping a Collection Iterator up as a SimpleFeatureCollection.
SortedSimpleFeatureCollection	A wrapper that will sort a feature collection using a size sensitive algorithm, in main memory for small collections, using secondary memory otherwise.
SubFeatureCollection	Reasonable default implementation for subCollection making use of parent SimpleFeatureCollection.features() and provided Filter.
SubFeatureList	Default implementation of FeatureCollection.sort(SortBy).
