Class DelegateFeatureIterator<F extends Feature>

Object
DelegateFeatureIterator<F>
All Implemented Interfaces:
Closeable, AutoCloseable, FeatureIterator<F>
Direct Known Subclasses:
DelegateSimpleFeatureIterator

public class DelegateFeatureIterator<F extends Feature> extends Object implements FeatureIterator<F>
A feature iterator that completely delegates to a normal Iterator, simply allowing Java 1.4 code to escape the caste (sic) system.

This implementation checks the iterator to see if it implements Closeable in order to allow for collections that make use of system resources.
