Interface FeatureIterator

All Known Implementing Classes:

DelegateFeatureIterator, FeatureIteratorImpl

public interface FeatureIterator

A drop in replacement for Iterator that does not require casting for Java 1.4 code.

We are sorry but this does not implement Iteartor, although it should be a drop in replacement when Geotools is able to upgrade to Java 5.
